i want to change date format from 2021-30-06T05:00:00+07:00 to get only time with format hh:mm:ss, but i didn't get it.
here is my code i already try
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"
dateFormatter.timeZone = NSTimeZone(name: "GMT+7")
let date = dateFormatter.dateFromString("2021-30-06T05:00:00+07:00")
// change to a readable time format and change to local time zone
dateFormatter.dateFormat = "HH:mm:ss"
dateFormatter.timeZone = NSTimeZone.localTimeZone()
let timeStamp = dateFormatter.stringFromDate(date!)
print(timeStamp)
Your 2021-30-06T05:00:00+07:00 is not matching with yyyy-MM-dd'T'HH:mm:ss.
Date format should be yyyy-dd-MM'T'HH:mm:ssZZZZZ.
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-dd-MM'T'HH:mm:ssZZZZZ"
let date = dateFormatter.date(from: "2021-30-06T05:00:00+07:00")
// change to a readable time format and change to local time zone
dateFormatter.dateFormat = "HH:mm:ss"
dateFormatter.timeZone = TimeZone.current
let timeStamp = dateFormatter.string(from: date!)
print(timeStamp)
Output:
03:30:00 // This is as per my current timezone.
let dateFormatter = DateFormatter()
dateFormatter.dateStyle = .medium
dateFormatter.timeStyle = .none
dateFormatter.locale = Locale.current
print(dateFormatter.string(from: post.createdDate))
Use DateFormatter instead of NSDateFormatter
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-dd-MM'T'HH:mm:ssZZZZZ"
let yourDate = dateFormatter.date(from: "2021-30-06T05:00:00+07:00")
// change to local time zone from your format
dateFormatter.dateFormat = "dd MMMM yyyy HH:mm:ss"
dateFormatter.timeZone = TimeZone.current
let DateString = dateFormatter.string(from: yourDate!)
print(DateString)
I am using swift 4. I need to convert my UTC Time to local time.But it shows two hour before. I am now Living in dhaka with GMT+6. Here is code i used ..
var date:String = "2020-02-10 14:30:57 PM"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd H:mm:ss a"
dateFormatter.timeZone = TimeZone(abbreviation: "UTC")
let dt = dateFormatter.date(from: date)
dateFormatter.timeZone = TimeZone.current
dateFormatter.dateFormat = "yyyy-MM-dd h:mm a"
let convertedLocalTime = dateFormatter.string(from: dt!)
tv_time.text = convertedLocalTime
print("convertedLocalTime-->",convertedLocalTime)
It shows 2020-02-10 6:30 PM But now 8.30 PM . What is the wrong with the code
Please help me
Your input data is not correctly formatted.
If you can use a correct format for the input data:
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd H:mm:ss"
dateFormatter.timeZone = TimeZone(abbreviation: "UTC")
// set the date in UTC
let date = dateFormatter.date(from: "2020-02-10 14:30:57")
dateFormatter.timeZone = TimeZone.current
// String representation of the date for local time
let s = dateFormatter.string(from: date!)
this snippet sets s to "2020-02-10 15:30:57" which is correct for Germany.
Otherwise you have to correct the format of your input data, e.g. delete the "PM" from the 24h format string.
I'm trying to change format my date for in-app purchases but returns nil in real devices but in simulator it working great.
let DateString = "2016-01-21 00:29:09 Etc/GMT"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss VV"
var dateObject = dateFormatter.date(from: DateString)
print(dateObject)
You should always set the locale of your DateFormatter when dealing with hardcoded Date formats. You can use en_US_POSIX in most scenarios.
let dateString = "2016-01-21 00:29:09 Etc/GMT"
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss VV"
let dateObject = dateFormatter.date(from: dateString)
print(dateObject)
I solved like this. maybe it's helps
formatter.amSymbol = "AM"
formatter.pmSymbol = "PM"
Why does DateFormatter return nil?
I think the string format matches?
let dateString = ("01/05/2017")!
let dateFormatter = DateFormatter()
dateFormatter.timeZone = TimeZone.current
dateFormatter.dateFormat = "dd/MMM/yyyy"
let dateObj = dateFormatter.date(from: dateString)
After executing the code above, the dateObj is nil.
For month you need to use MM because MMM is used when you having month in the format like Jan,Feb,Mar and so on. So your dateFormat should be dd/MM/yyyy.
let dateString = "01/05/2017"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd/MM/yyyy"
let dateObj = dateFormatter.date(from: dateString)
Note: No need to set timeZone to TimeZone.current
Replace with your dateFormat:
dateFormatter.dateFormat = "dd/MM/yyyy"
date Formatter should be dateFormatter.dateFormat = "dd/MM/yyyy" in this case.
You can check various date format from given link
NSDateFormatter
For given example you can use let formaterStrig = "dd/MM/yyyy"
I am trying to convert an am/pm format time to a 24 hour format time
6:35 PM to 18:35
I tried this piece of code on playground but it doesn't seem to
work if I put the time alone
let dateAsString = "02/12/15, 6:35 PM"
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "HH"
let date = dateFormatter.dateFromString(dateAsString) //returns nil
Does anyone know how to accomplish this?
Just convert it to a date using NSDateFormatter and the "h:mm a" format and convert it back to a string using the "HH:mm" format. Check out this date formatting guide to familiarize yourself with this material.
let dateAsString = "6:35 PM"
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "h:mm a"
dateFormatter.locale = Locale(identifier: "en_US_POSIX") // fixes nil if device time in 24 hour format
let date = dateFormatter.dateFromString(dateAsString)
dateFormatter.dateFormat = "HH:mm"
let date24 = dateFormatter.stringFromDate(date!)
Swift 3
Time format 24 hours to 12 hours
let dateAsString = "13:15"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "HH:mm"
let date = dateFormatter.date(from: dateAsString)
dateFormatter.dateFormat = "h:mm a"
let Date12 = dateFormatter.string(from: date!)
print("12 hour formatted Date:",Date12)
output will be 12 hour formatted Date: 1:15 PM
Time format 12 hours to 24 hours
let dateAsString = "1:15 PM"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "h:mm a"
let date = dateFormatter.date(from: dateAsString)
dateFormatter.dateFormat = "HH:mm"
let Date24 = dateFormatter.string(from: date!)
print("24 hour formatted Date:",Date24)
output will be 24 hour formatted Date: 13:15
Swift 3 *
Code to convert 12 hours (i.e. AM and PM) to 24 hours format which includes-
Hours:Minutes:Seconds:AM/PM to Hours:Minutes:Seconds
func timeConversion24(time12: String) -> String {
let dateAsString = time12
let df = DateFormatter()
df.dateFormat = "hh:mm:ssa"
let date = df.date(from: dateAsString)
df.dateFormat = "HH:mm:ss"
let time24 = df.string(from: date!)
print(time24)
return time24
}
Input
07:05:45PM
Output
19:05:45
Similarly
Code to convert 24 hours to 12 hours (i.e. AM and PM) format which includes-
Hours:Minutes:Seconds to Hours:Minutes:Seconds:AM/PM
func timeConversion12(time24: String) -> String {
let dateAsString = time24
let df = DateFormatter()
df.dateFormat = "HH:mm:ss"
let date = df.date(from: dateAsString)
df.dateFormat = "hh:mm:ssa"
let time12 = df.string(from: date!)
print(time12)
return time12
}
Input
19:05:45
Output
07:05:45PM
Below is the swift 3 version of the solution -
let dateAsString = "6:35:58 PM"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "h:mm:ss a"
let date = dateFormatter.date(from: dateAsString)
dateFormatter.dateFormat = "HH:mm:ss"
let date24 = dateFormatter.string(from: date!)
print(date24)
Here is the answer with more extra format.
** Xcode 12, Swift 5.3 **
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "HH:mm:ss"
var dateFromStr = dateFormatter.date(from: "12:16:45")!
dateFormatter.dateFormat = "hh:mm:ss a 'on' MMMM dd, yyyy"
//Output: 12:16:45 PM on January 01, 2000
dateFormatter.dateFormat = "E, d MMM yyyy HH:mm:ss Z"
//Output: Sat, 1 Jan 2000 12:16:45 +0600
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ"
//Output: 2000-01-01T12:16:45+0600
dateFormatter.dateFormat = "EEEE, MMM d, yyyy"
//Output: Saturday, Jan 1, 2000
dateFormatter.dateFormat = "MM-dd-yyyy HH:mm"
//Output: 01-01-2000 12:16
dateFormatter.dateFormat = "MMM d, h:mm a"
//Output: Jan 1, 12:16 PM
dateFormatter.dateFormat = "HH:mm:ss.SSS"
//Output: 12:16:45.000
dateFormatter.dateFormat = "MMM d, yyyy"
//Output: Jan 1, 2000
dateFormatter.dateFormat = "MM/dd/yyyy"
//Output: 01/01/2000
dateFormatter.dateFormat = "hh:mm:ss a"
//Output: 12:16:45 PM
dateFormatter.dateFormat = "MMMM yyyy"
//Output: January 2000
dateFormatter.dateFormat = "dd.MM.yy"
//Output: 01.01.00
//Output: Customisable AP/PM symbols
dateFormatter.amSymbol = "am"
dateFormatter.pmSymbol = "Pm"
dateFormatter.dateFormat = "a"
//Output: Pm
// Usage
var timeFromDate = dateFormatter.string(from: dateFromStr)
print(timeFromDate)
Swift version 3.0.2 , Xcode Version 8.2.1 (8C1002) (12 hr format ):
func getTodayString() -> String{
let formatter = DateFormatter()
formatter.dateFormat = "h:mm:ss a "
formatter.amSymbol = "AM"
formatter.pmSymbol = "PM"
let currentDateStr = formatter.string(from: Date())
print(currentDateStr)
return currentDateStr
}
OUTPUT : 12:41:42 AM
Feel free to comment. Thanks
Use this function for date conversion, its working fine when your device in 24/12 hr format
See https://developer.apple.com/library/archive/qa/qa1480/_index.html
func convertDateFormatter(fromFormat:String,toFormat:String,_ dateString: String) -> String{
let formatter = DateFormatter()
formatter.locale = Locale(identifier: "en_US_POSIX")
formatter.dateFormat = fromFormat
let date = formatter.date(from: dateString)
formatter.dateFormat = toFormat
return date != nil ? formatter.string(from: date!) : ""
}
Unfortunately apple priority the device date format, so in some cases against what you put, swift change your format to 12hrs
To fix this is necessary to use setLocalizedDateFormatFromTemplate instead of dateFormat an hide the AM and PM
let formatter = DateFormatter()
formatter.setLocalizedDateFormatFromTemplate("HH:mm:ss a")
formatter.amSymbol = ""
formatter.pmSymbol = ""
formatter.timeZone = TimeZone(secondsFromGMT: 0)
var prettyDate = formatter.string(from: Date())
You can check a very useful post with more information detailed in
https://prograils.com/posts/the-curious-case-of-the-24-hour-time-format-in-swift
Here is code for other way around
For Swift 3
func amAppend(str:String) -> String{
var temp = str
var strArr = str.characters.split{$0 == ":"}.map(String.init)
var hour = Int(strArr[0])!
var min = Int(strArr[1])!
if(hour > 12){
temp = temp + "PM"
}
else{
temp = temp + "AM"
}
return temp
}
let calendar = Calendar.current
let hours = calendar.component(.hour, from: Date())
let minutes = calendar.component(.minute, from: Date())
let seconds = calendar.component(.second, from: Date())
I am using a function here in my case by which I am updating a label with the normal time format and after that I am storing the selected time's 24hr format to do some another tasks..
Here is my code...
func timeUpdate(sender: NSDate)
{
let timeSave = NSDateFormatter() //Creating first object to update time label as 12hr format with AM/PM
timeSave.timeStyle = NSDateFormatterStyle.ShortStyle //Setting the style for the time selection.
self.TimeShowOutlet.text = timeSave.stringFromDate(sender) // Getting the string from the selected time and updating the label as 1:40 PM
let timeCheck = NSDateFormatter() //Creating another object to store time in 24hr format.
timeCheck.dateFormat = "HH:mm:ss" //Setting the format for the time save.
let time = timeCheck.stringFromDate(sender) //Getting the time string as 13:40:00
self.timeSelectedForCheckAvailability = time //At last saving the 24hr format time for further task.
}
After writing this function you can call this where you are choosing the time from date/time picker.
Thanks,
Hope this helped.
this is similar to our friends answer: https://stackoverflow.com/a/43801717/2796837 but using all our internet friends ideas I came up with the following more complete singular solution:
let amPmFormat = "h:mm a"
let twentyFourHFormat = "HH:mm"
func hourMinuteParser(date: Date) -> KotlinInt{
let formatter = DateFormatter()
if DateFormatter.dateFormat(fromTemplate: "j",options:0, locale: Locale.current)!.contains("a") {
formatter.dateFormat = amPmFormat
}else{
formatter.dateFormat = twentyFourHFormat
}
let stringTime = formatter.string(from: date)
let time = formatter.date(from: stringTime)
formatter.dateFormat = twentyFourHFormat
let time24 = formatter.string(from: time!)
let timeWithoutSpecialCharacters = time24.replacingOccurrences(of: ":", with: "")
let int2 = Int32(timeWithoutSpecialCharacters) ?? 0
return KotlinInt(int: int2)
}
This will parse your time even independent of the format it comes and outputs it into HH:mm, you could change the third format change into whatever you would want.
