The setTimestamp Method of the DateTime Class
The setTimestamp method of the DateTime object allows you to set the date and time,
using a Unix timestamp (the number of seconds since January 1, 1970).
The method modifies the existing date object and returns it for method chaining.
Syntax
public DateTime::setTimestamp(int $timestamp): DateTime
Example
Let's set the date corresponding to the timestamp 1609459200
(January 1, 2021, 00:00:00 UTC):
<?php
$date = new DateTime();
$date->setTimestamp(1609459200);
echo $date->format('Y-m-d H:i:s');
?>
Code execution result:
'2021-01-01 00:00:00'
Example
Usage in method chains:
<?php
$date = (new DateTime())->setTimestamp(1609459200);
echo $date->format('Y-m-d');
?>
Code execution result:
'2021-01-01'
Example
Setting the current time:
<?php
$date = new DateTime();
$date->setTimestamp(time());
echo $date->format('H:i:s');
?>
Will output the current time, for example:
'14:25:36'
