Test script: --------------- // UTC+5 $date = new DateTime( 'now', new DateTimezone( 'Asia/Yekaterinburg' ) ); echo $date->format( 'U' ) . "\n"; // UTC+3 $date = new DateTime( 'now', new DateTimezone( 'Europe/Moscow' ) ); echo $date->format( 'U' ); Expected result: ---------------- 1284734980 1284727780 Actual result: -------------- 1284727780 1284727780 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52870&edit=1
