php - One Hour Earlier Than Given Datetime

Question

I\'m having a problem here..

Supposed I have this kind of datetime.

$date = strtotime($date);

I need this to be converted into t

Answer 1

86400 seconds is one DAY, not one hour.

The output of strtotime() is a unix timestamp. 3600 seconds earlier is that timestamp minus one hour. So:

$date = strtotime($somestring);

$hourago = $date - 3600;

Or, depending on the original format of $somestring:

$hourago = strtotime($somestring . " - 1 hour");

And don't forget about date_default_timezone_set()
