When parsing date and time from an API call which is formatted like this 2018 - 04 - 18T21:51:00 I get and error that states
and I don't understand what am I doing wrong.
/// I set in which format should my data be, and parse the data from the API call
Text('Date and Time:
${DateFormat("yyyy-MM-dd hh:mm:ss").format(DateTime.parse(apicall.timeanddate))}'),
After that I would format the Date and Time according to Locale language preference of the device.
Any help is appreciated.
The format you are passing is invalid, so you need to transform it:
String getDateTime(String dateFromServer){
dateFromServer = dateFromServer.replaceAll(" ","");
dateFromServer = dateFromServer.replaceAll("T"," ");
return dateFromServer;
}
I replaced all spaces and T that were causing problems you can now use this with:
DateFormat("yyyy-MM-dd hh:mm:ss").format(getDateTime(apicall.timeanddate));
Hope this would solve your problem.

I have a date which is a string and looks like this:
String day = "30-11-2022 12:27";
I am trying to convert the above string to DateTime object and convert the 24hr time to 12hr. I am using the following code:
DateFormat("dd-MM-yyyy hh:mm a").parse(day);
It was working before but today the parsing is causing format exception error. The error message is shown below:
[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: FormatException: Trying to read from 30-11-2022 12:27 at position 17
Why am I getting error while parsing now? How to fix it?
There must be a simpler solution, but it works this way:
final str = "30-11-2022 12:27";
final date = DateFormat("dd-MM-yyyy hh:mm").parse(str);
final formated = DateFormat("dd-MM-yyyy h:mm a").format(date);
The format for a 24-hr time is 'HH:mm'. The key is to call add_jm(). Just do this:
final day = '30-11-2022 12:27';
final dateTime = DateFormat('dd-MM-yyyy HH:mm').parse(day);
final formatted = DateFormat('dd-MM-yyy').add_jm().format(dateTime);
print(formatted);
The output is:
30-11-2022 12:27 PM
can try this. hope your problem solved
DateTime dateTime = DateFormat('yyyy/MM/dd h:m').parse(date);
final DateFormat formatter = DateFormat('yyyy-MM-dd h:m a');
final String formatted = formatter.format(dateTime);
It really doesn't matter for datetime that the input date is in am format or not, because you can parse it to what ever format you want. For both option when you parse your string, it will save it in regular form. So just try this:
String day = "30-11-2022 12:27";
DateTime date = normalFormat.parse(day);
and when ever you want show it as AM, just format date;
Why am I getting error while parsing now? How to fix it?
You specified a DateFormat format string that uses a, which indicates that you want to parse an AM/PM marker, but the string you try to parse is "30-11-2022 12:27", which lacks it.
If you're trying to convert a 24-hour time to a 12-hour time, those are fundamentally two different formats, so you will two different DateFormat objects. Note that the format pattern for hours is different for 12-hour times (h) than for 24-hour ones (H):
String day = "30-11-2022 12:27";
var datetime = DateFormat("dd-MM-yyyy HH:mm").parse(day);
// Prints: 30-11-2022 12:27 PM
print(DateFormat('dd-MM-yyyy hh:mm a').format(datetime));
To preface I'm very new at this but I currently have a script that outputs a Google Doc/PDF based on inputs into my google form.
The PDF is output whenever a new form is submitted, currently the formatting for the date comes out as DD/MM/YY but I want it to appear as dd MMMM yyyy i.e. 19 May 2020 rather than 19/05/20.
I've tried using the following to change the formatting
var signDate = e.values[1];
var formatSignDate = Utilities.formatDate(signDate, "GMT+1", "dd MMMM yyyy");
body.replaceText('{{Execution Date}}', formatSignDate);
But I get the following error
Exception: The parameters (String,String,String) don't match the method signature for Utilities.formatDate.
at autoFillFromForm(Code:17:28)
What am I doing wrong? Can I not use .formatDate with the date from my sheets cells?
Edit: error message with log of signDate
Stackdriver logs Info signDate = 20/05/2020 Error Exception: The parameters
(String,String,String) don't match the method signature for
Utilities.formatDate. at autoFillFromForm(Code:23:34)
Exception: The parameters (String,String,String) don't match the method signature for Utilities.formatDate
means that signDate is not recognized correctly as a date object
Please provide a log of signDate to help you troubleshoot more in detail.
UPDATE
If you have a date string in UK format ( DD/MM/YYYY), it won't be automatically recognized as a Javascript date object.
You'll need to convert it, e.g:
var convertedDate = new Date(signDate.split('/')[2], signDate.split('/')[1] - 1, signDate.split('/')[0]);
Logger.log(convertedDate);
var formatSignDate = Utilities.formatDate(convertedDate, "GMT+1", "dd MMMM yyyy");
Logger.log(formatSignDate);
Note: Using Utilities.formatDate() as above might give you the wrong date if you are setting it to a different timezone than your script time zone.
I have a component that uses a datepicker. The datepicker needs a dateFormat property that fits the momentjs pattern, for example 'DD.MM.YYYY' or 'MM/DD/YYYY'.
The date formatting is handled by react-intl. This works fine when converting from a date to a string (via formatDate). However, I need to retrieve the pattern as described above.
My goal is to do something like
dateFormat = this.props.intl.extractDateFormat() // returns 'DD.MM.YYYY'
I have found this similar question, but the only answer relies on parsing the string, which I cannot do, because I do not know whether Day or Month will come first in the formatted date.
If it is possible to convert this string to a date and somehow retrieve the format from momentjs, that would also be a good solution.
I was able to get the date format from react-intl. To do this, I defined an example date and had it formatted by react-intl, and then parsed the format by referring to the original string.
My component which is exported as injectIntl(Component) has this method:
deriveDateFormat = () => {
const isoString = '2018-09-25' // example date!
const intlString = this.formatDate(isoString) // generate a formatted date
const dateParts = isoString.split('-') // prepare to replace with pattern parts
return intlString
.replace(dateParts[2], 'DD')
.replace(dateParts[1], 'MM')
.replace(dateParts[0], 'YYYY')
}
The date will e.g. be formatted to '09/25/2018', and this function would return 'MM/DD/YYYY', a format which can be used by Moment.js.
This function only works if you know that the month and day will always be displayed with two digits. It would fail if the format is something like 9/25/2018.
I have not found a way to extract the date format from react-intl directly.
With apex, I pass a string like:
2017-02-05T01:44:00.000Z
to an apex function from javascript, however, when attempting to turn it into a datetime, it gives me invalid date/time error. I can create a date with it like
date newdate = date.valueOf(dateString);
but if I do datetime newdate = datetime.valueOf(dateString) I get the error. I don't get why it sees the string as incorrectly formatted to give invalid date/time. When I create just a date instead of datetime, I lose the time and it sets it to 00:00:00.
Thank you to anyone with some insight on how to create the datetime in apex! I have been trying to find the apex format and from what I see. I can't understand why it thinks this is invalid.
Try this.
String inpputString = '2017-02-05T01:44:00.000Z';
DateTime resultDateTime = DateTime.ValueofGmt(inpputString.replace('T', ' '));
System.Debug('resultDateTime>> '+resultDateTime);
Output:
10:10:41:011 USER_DEBUG [4]|DEBUG|resultDateTime>> 2017-02-05 01:44:00
let's say I have a Date as a String, formated in yyyy-MM-dd, and I want it to be formated as style:"short".
I want just to use Dateformat.
I used this https://openui5.hana.ondemand.com/#docs/guide/91f2eba36f4d1014b6dd926db0e91070.html to get an idea of how to use DateFormat.
But I can't see, what's wrong with my code:
date: function(sdate) {
var regex = "[0-9]{4}-[0-9]{2}-[0-9]{2}";
if (!sdate.match(regex))
return "no valid date given";
jQuery.sap.require("sap.ui.core.format.DateFormat");
var oDateFormat = sap.ui.core.format.DateFormat.getInstance({pattern: "yyyy-MM-dd", style: "short"});
return oDateFormat.format(sdate); //date should be returned here in "short"-style
}
The console tell's me
TypeError: j.getTime is not a function.
Also it seems like the WebIDE doesn't know a function Datetime.format().
Can you help?
You'd probably reread the documentation in your link: to convert String into JS Date, you have to use DateFormat.parse method.
