gmdate and time

What is this code doing?
Code: Select all
$req->StartTimeFrom = gmdate('Y-m-d H:i:s', time() - 60 * 60 * 24 * 15);
$req->StartTimeTo = gmdate('Y-m-d H:i:s');
It looks like its creating a date range....how could I adjust the date range?
Thanks

StartTimeFrom is a date and time in the past. StartTimeTo is the current date and time. Both are shifted to Greenwich time.

I live in the central time zone in the United States. I think it is +6 difference relative to GMT. How would I convert the current GMT to my time zone?

Use
date() or subtract six hours from the time given to the function.

Like this?
Code: Select all
function toGMT($time){
//set to local time zone relative to GMT (+6 for US CST)
$step = 6;
$mytime = substr($time,11);
$time_array = explode(":",$mytime);
$mydate = substr($time,0,10);
$date_array = explode("-",$mydate);
$newtime = date("Y-m-d H:i:s",mktime($time_array[0]-$step,$time_array[1],$time_array[2],$date_array[1],$date_array[2],$date_array[0]));
return $newtime;
}

Yes it works...just wanted to see if it was the best way.

It's a way. I can't say whether it's the best way, nor does it really matter.

Code: Select all
$time-=6*60*60; // if $time is a timestamp
$time = date("Y-m-d H:i:s",strtotime($time.' -6 hours')); // if time begins in the other format
