How to Convert UTC Date and Time to Local Time in JavaScript and jQuery?

Converting UTC Date Time to Local Date Time

When receiving a datetime variable from the server in UTC format, the need arises to convert it to the current user's browser time zone for accurate display. This guide provides a JavaScript or jQuery-based solution for this task.

JavaScript Conversion

To convert a UTC datetime string in JavaScript, follow these steps:

1. Append the string 'UTC' to the original datetime:

2. Create a new Date object using the modified string:

3. The resulting date object will represent the local time equivalent of the original UTC datetime.

Example:

utcDateTime = '6/29/2011 4:52:48 PM UTC';
date = new Date(utcDateTime);

The output `Wed Jun 29 2011 09:52:48 GMT-0700 (PDT)` represents the local time in the user's browser, corresponding to 4:52:48 PM UTC.

**jQuery Conversion**

jQuery provides a similar method for UTC datetime conversion:

>```
var date = $.datepicker.parseDate('utc', '6/29/2011 4:52:48 PM UTC');

The resulting date variable will contain the local time equivalent of the UTC datetime.

Note: The example shown assumes the user's time zone is Pacific Daylight Time (PDT). The actual local time displayed will vary based on the user's browser time zone settings.
