[php] timestamp 0 sekund vrne 01:00:00 zakaj?

Ni mi jasno zakaj dobim tole: (psevdokoda)

date("H:i:s", 0 sekund) = 01:00:00
date("H:i:s", 1800 sekund) = 01:30:00 .......

oz kaj bi naredil da vrne 00:00:00

Hvala za namig?

date ti vrne oblikovan niz, glede na drugi parameter, timestamp. v manualu je tole zraven:

The valid range of a timestamp is typically from Fri, 13 Dec 1901 20:45:54 GMT to Tue, 19 Jan 2038 03:14:07 GMT. (These are the dates that correspond to the minimum and maximum values for a 32-bit signed integer). On Windows this range is limited from 01-01-1970 to 19-01-2038.

date ("neki", 0) ti torej vrne cas, ko bi timestamp vrnil 0, se pravi nekje v prejsnjem tisocletju. ocitno so zacel stet ob enih zjutrej :) moral se bos problema drugace lotit. ce mas to kot neke vrste stoparico al kej tazga, lahko poskusis s kakim trikom, npr:

$diff = $t2 - $t1;
$diff += 23 * 60 * 60;
$date = date("H:i:s", $diff);
