I am pulling a timeStamp from the database that basically has a value similar to this 2020-08-13 21:51:50, is there a way to convert this timeStamp to time ago?
You can use the timeago package.
import 'package:timeago/timeago.dart' as timeago;
print(timeago.format(DateTime.parse('2020-08-13 21:51:50')));
JideGuru is correct on how to use the timeago package; however, if you are pulling the timestamp from a MySQL database you may need to convert it to toDate first:
import 'package:timeago/timeago.dart' as timeago;
var rawTime = mySQLTimestamp.toDate();
String timeAgoTime = timeago.format(rawTime);

I would like to know how a date such as "2022-07-17T01:46:12.632892+05:30" be converted to a Human Readable date in DD/MM/YYYY and hh:mm:ss format? I probably have not surfed through a lot of other questions and suggestions on the Internet but the ones I came across were not of any help. Also, what are such date formats(like the one in question) called?
It is rather straightforward using DateFormat from the package intl which comes with Flutter:
import 'package:intl/intl.dart';
void main() {
final dateTime = DateTime.parse('2022-07-17T01:46:12.632892+05:30').toUtc();
final dateFormat = DateFormat('dd/MM/yyyy HH:mm:ss');
print(dateFormat.format(dateTime)); // 16/07/2022 20:16:12
}
The time has here been converted to UTC to make the example the same for all readers. If not, the created DateTime would be localtime which uses the timezone on the device which the program are running.
If you want to print the time using the timezone offset of 5 hours and 30 minutes, you can do something like this:
import 'package:intl/intl.dart';
void main() {
final dateTime = DateTime.parse('2022-07-17T01:46:12.632892+05:30').toUtc();
final dateFormat = DateFormat('dd/MM/yyyy HH:mm:ss');
print(dateFormat.format(dateTime.add(const Duration(hours: 5, minutes: 30))));
// 17/07/2022 01:46:12
}
how to show datetime(timestamp format) form firebase firestore in (dd/mm/yy, hh:mm:ss) in flutter.
please see the images attachedfirebase firestore data
and my code is my code in vscode
You can simply call toDate() function to the dateTime or your firebase timestamp.
You can also convert them into desired format by using DateFormat class
Here is a small function which will return time like 12:37 AM :
import 'package:intl/intl.dart'; //add this import statement for using DateTime class
String getTime(var time) {
final DateFormat formatter = DateFormat('dd/MM/yyyy, hh:mm:ss aa'); //your date format here
var date = time.toDate();
return formatter.format(date);
}
This function will convert your timestamp object to provided format
eg.: July 23, 2021 at 9:22:29 PM UTC+5:30 -> 23/07/2021, 9:22:29 PM
You can refer this document for detailed date formatting.
You can first parse the date to get a DateTime object by using DateTime.parse(string_from_firebase).
Then use the DateFormat class from the intl package.
final DateTime dateToBeFormatted = DateTime.parse(string);
final df = DateFormat('dd/MM/yyyy');
final formatted = df.format(dateToBeFormatted);
I cannot get any NSE Symbol data from the AlphaVantage, they return always empty array.
Query:
https://www.alphavantage.co/query?function=TIME_SERIES_INTRADAY&symbol=NSE:TITAN&apikey=Q134IXR7RVWU5AQL&outputsize=full&interval=1min
Response:
{}
A month back the same query was returning data.
Looks something has changed on the AlphaVantage server end recently.
Your help is much appreciated in advance!
Try this
import pandas as pd
import json
import requests
import datetime
from pandas import DataFrame
from datetime import datetime as dt
from alpha_vantage.timeseries import TimeSeries
stock_ticker = 'SPY'
api_key = 'Q134IXR7RVWU5AQL'
ts = TimeSeries (key=api_key, output_format = "pandas")
data_daily, meta_data = ts.get_intraday(symbol=stock_ticker, interval ='1min', outputsize ='full')
print(data_daily)
The output for me looks like this
I have a set of dates stored as UTC in my database, when I import them in Salesforce using the tSalesforceOutput:
If I run the import from my machine, they get the wrong timezone
If I run the import from a server which is in UTC, they get the correct timezone.
Is Talend/Salesforce API using the local timezone? How can I prevent this?
Salesforce will allways convert datetime from user timezone to UTC before to store them.
To avoid any problem, the simpler is to fix the user timezone used for the Salesforce connection to GMT and to explicitly convert each datetime to this timezone before to call any tSalesforceOutputXxxx component.
Here is a routine you can use for this purpose:
package routines;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.TimeZone;
public class dateConversion {
public static String convertToGmt(String strDate, String timezone) throws Exception
{
if (strDate == null || timezone == null)
return null;
// Convert strDate from any valid TimeZone such as Europe/Paris to GMT
// strDate is expected to be formatted as "yyyy-MM-ddTHH:mm:ssZ"
SimpleDateFormat indfm = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
indfm.setTimeZone(TimeZone.getTimeZone(timezone));
Date inDate = indfm.parse(strDate);
SimpleDateFormat outdfm = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ");
outdfm.setTimeZone(TimeZone.getTimeZone("GMT"));
String s = outdfm.format(inDate);
return s;
}
}
Hope this helps.

I have to find the last date of the last month
I am using a Groovy Script
I can get the date part ok but now I have to turn it into a String in the form yyyyMMdd.
Code so far (and yes it works)
import java.util.GregorianCalendar;
import java.util.Calendar;
import java.util.Date;
Calendar aCalendar = Calendar.getInstance();
// add -1 month to current month
aCalendar.add(Calendar.MONTH, -1);
// set actual maximum date of previous month
aCalendar.set(Calendar.DATE,aCalendar.getActualMaximum(Calendar.DAY_OF_MONTH));
//read it
lastDateOfPreviousMonth = aCalendar.getTime();
This returns the date in timestamp form
20160229 105925.240
Now I need to extract 20160229 from the timestamp as a string
I've tried just about everything...
If this is running on Java 8, you can use the new Java Time classes:
import java.time.LocalDate
import java.time.format.DateTimeFormatter
import java.time.temporal.TemporalAdjusters
String date = LocalDate.now()
.minusMonths(1)
.with(TemporalAdjusters.lastDayOfMonth())
.format(DateTimeFormatter.ofPattern("yyyyMMdd"))
If this is Java 7 or Java 6, you can use Calendar and a bit of Groovy:
String date = Calendar.instance.with {
add(MONTH, -1)
set(DAY_OF_MONTH, getActualMaximum(DAY_OF_MONTH))
time
}.format('yyyyMMdd')
