gmdate() - want 1 hr before time

[rupam_jaiswal]

Hi,
I am using php gmdate().
Now I am entering all dates in my dbase using gmdate("Y-m-d H:i:s")
I want 1 hr before datetime.
So am using like
gmdate("Y-m-d H:i:s", mktime(gmdate("H")-$hrs, gmdate("i"), gmdate("s"), gmdate("m"), gmdate("d"), gmdate("Y")));
where $hr = 1
When I echo current date i,e

$date = gmdate('Y-m-d H:i:s');
echo "<br/>current date is $date";

its
2009-12-27 03:54:08

and when echo my code of getting 1 hr before
$date1 = gmdate("Y-m-d H:i:s", mktime(gmdate("H")-1, gmdate("i"), gmdate("s"), gmdate("m"), gmdate("d"), gmdate("Y")));

its
2009-12-26 02:54:08

difference between these 2 days is 1 day and not 1 hr.
I want 1 hr before datetime to be
2009-12-27 02:54:08

Can please anybody help.
Thanks in advance

mktime() uses the local timezone. You want [man]gmmktime[/man]. Better yet,

strtotime('1 hour ago');

does the whole job.

Thanks for your help.
Am using gmmktime 🙂

It might be more efficient to use gmdate('Y-m-d H:i:s', time()-3600).
