Question

Given a time, how can I find the time one month ago.

Answer 1

We can achieve same by using PHP's modern date handling. This will require PHP 5.2 or better.

// say its "2015-11-17 03:27:22"
$dtTm = new DateTime('-1 MONTH', new DateTimeZone('America/Los_Angeles')); // first argument uses strtotime parsing
echo $dtTm->format('Y-m-d H:i:s'); // "2015-10-17 03:27:22"

Hope this adds some more info for this question.
