How to Convert UTC Epoch to Local Date?

Convert UTC Epoch to Local Date: A Comprehensive Solution

The challenge of converting a UTC epoch to a local date arises when the default behavior of the Date() constructor assumes local epoch. This can lead to inaccuracies in date representation.

To address this issue, a more robust approach can be employed:

Solution:

1. Initialize a Date object to the epoch (0):

var d = new Date(0);

2. Convert the UTC epoch to seconds:

var utcSeconds = // Replace with your UTC epoch in seconds

3. Set the UTC seconds using the Date object's setUTCSeconds method:

d.setUTCSeconds(utcSeconds);

This approach ensures that the resulting date, stored in the "d" variable, represents the specified UTC epoch in the local time zone.

Example:

Consider a UTC epoch of 1234567890:

var utcSeconds = 1234567890;
var d = new Date(0);
d.setUTCSeconds(utcSeconds);

The "d" variable will now hold the local date equivalent to this UTC epoch: Fri Feb 13 2009 18:31:30 GMT-0500 (EST).
