php - date('Z') for a specific date (not for now) -

date('z') - timezone offset in seconds. offset timezones west of utc negative, , east of utc positive.

so offset (this moment of time).

is there way offset in seconds specific time (for ex: 2012-02-17 12:00).

i aware can achieve using datetime class. possible achieve using date() only?

edit:

if server in toronto , it's summer => date('z') => -14400

if server in toronto , it's winter => date('z') => -18000

use strtotime date:

$getdate = '2012-02-17 12:00'; date('z',strtotime($getdate));
