PHP timestamp basics
PHP timestamps usually represent seconds since January 1, 1970 UTC. When comparing with JavaScript, remember that JavaScript uses milliseconds.
PHP example
date_default_timezone_set('UTC');
echo date('Y-m-d H:i:s', 1719820800);Common mistakes
Passing a JavaScript millisecond timestamp into PHP without dividing by 1000 will produce a date far in the future.
FAQ
Does PHP use seconds or milliseconds?

Why does local time differ from UTC?
