### Description

public DateTimeImmutable::setTimestamp(int `$timestamp`): DateTimeImmutable

Returns a new DateTimeImmutable object constructed from the old one, with the date and time set based on an Unix timestamp.

  Unix timestamp representing the date. Setting timestamps outside the range of int is possible by using DateTimeImmutable::modify() with the `@` format.

### Return Values

### Examples

Example #1 DateTimeImmutable::setTimestamp() example

Object-oriented style

`<?php
$date = new DateTimeImmutable();
echo $date->format('U = Y-m-d H:i:s') . "\n";
$newDate = $date->setTimestamp(1171502725);
echo $newDate->format('U = Y-m-d H:i:s') . "\n";`

The above example will output something similar to:

    1272508903 = 2010-04-28 22:41:43
    1171502725 = 2007-02-14 20:25:25
