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 the Unix-timestamp format but one hour earlier..I tried

$date = strtotime($date-86400)

, but seemed to me it is wrong. It returned 0 when I sneaked into the table.

What is the appropriate way to achieve this?

Thanks.

You could do:

$testDateStr = strtotime($date);
$finalDate = date("Y-m-d H:i:s", strtotime("-1 hour", $testDateStr));

Hope it helps
