PHP date_default_timezone_set() Eastern Standard Time (EST)

Question

Long story short

Is there an official, un-deprecated timezone that PHP5 recognizes for Eastern STANDARD time--not Eastern DAYLIGHT time?

Answer 1

echo ' Format ' . date('m/d/Y H:i:s a') ;

//maketime function- mktime(hour,minute,second,month,day,year,is_dst)

$EasternTimeStamp =mktime(date('H')-6,date('i'),date('s'),date("m"),date("d"),date("Y"));

// date function- date(format, timestamp)

echo 'Format ' . date('m/d/Y H:i:s a',$EasternTimeStamp) ;
