How to convert Date to format “YYYY-MM-DDThh:mm:ss-hh:mm”?

21.2K Asked by CsabaToth in Java , Asked on Jun 2, 2021

I want to convert Date from "YYYY-MM-DD" to "YYYY-MM-DDThh:mm:ss-hh:mm" format in Apex. Ex. "2016-05-20" should be converted to "2016-05-20T00:00:00-00:00". Any help/suggestion is appreciated.

   I tried the "yyyy-MM-dd'T'HH:mm:ss.SSSXXX" pattern and I am able to convert Date from "YYYY-MM-DD" to "YYYY-MM-DDThh:mm:ss-hh:mm" format as given below-    Date d = System.today(); Datetime myDT = datetime.newInstance(d.year(), d.month(),d.day()); String myDate = myDT.format('yyyy-MM-dd'T'HH:mm:ss.SSSXXX');  "YYYY-MM-DDThh:mm:ss-hh:mm" is ISO 8601

for formatting and parsing dates.

yyyy-MM-dd HH:mm:ss,SSSXXX 1999-03-22 05:06:07,000+01:00

yyyy-MM-dd'T'HH:mm:ssXXX 1999-03-22T05:06:07+01:00

To convert a date into the format "YYYY-MM-DDThh:mm:ss-hh:mm", follow these steps based on your preferred programming language or tool:

1. Using JavaScript

You can use the toISOString() method and adjust the time zone offset:

function formatDate(date) {

    let offset = -date.getTimezoneOffset();

    let sign = offset >= 0 ? "+" : "-";

    let pad = (num) => String(Math.abs(num)).padStart(2, "0");

    return `${date.getFullYear()}-${pad(date.getMonth() + 1)}-${pad(date.getDate())}T` +

           `${pad(date.getHours())}:${pad(date.getMinutes())}:${pad(date.getSeconds())}${sign}` +

           `${pad(Math.floor(offset / 60))}:${pad(offset `)}`;

}

console.log(formatDate(new Date())); // Example Output: 2024-02-20T14:30:15+05:30

2. Using Python

The datetime module helps format the date properly:

from datetime import datetime, timezone

def format_date(dt):

    formatted_date = dt.astimezone().strftime('%Y-%m-%dT%H:%M:%S%z')

    return formatted_date[:-2] + ':' + formatted_date[-2:]  # Add colon in timezone offset

now = datetime.now(timezone.utc)

print(format_date(now)) # Example Output: 2024-02-20T14:30:15+00:00

3. Using Excel

If your date is in A1, use this formula:

  =TEXT(A1, "yyyy-mm-ddTHH:MM:SS") & TEXT((A1-NOW())*24, "+00:00")

4. Using SQL (MySQL Example)

  SELECT DATE_FORMAT(NOW(), '%Y-%m-%dT%H:%i:%s') AS formatted_date;

Key Points

The T separates date and time.
The -hh:mm at the end represents time zone offset.
Ensure your method accounts for time zone conversion.

To convert a date to the format "YYYY-MM-DDThh:mm:ss-HH:MM", you can use Python's strftime function to format the date string according to your desired format.

Here's an example:

import datetime

# Assuming your date is stored in a datetime object

date = datetime.datetime.now()

# Format the date to "YYYY-MM-DDThh:mm:ss-HH:MM"

formatted_date = date.strftime("%Y-%m-%dT%H:%M:%S-%H:%M")

print("Formatted date:", formatted_date)

This code snippet retrieves the current date and time using datetime.datetime.now() and then formats it using the strftime function with the specified format string "%Y-%m-%dT%H:%M:%S-%H:%M". Adjust the date variable accordingly if you're working with a different date.
