/**
|
||||||
|
* EGroupware time and timezone handling class extending PHP's DateTime
|
||||||
|
*
|
||||||
|
* Api\DateTime class knows 2 timezones:
|
||||||
|
* 1. Api\DateTime::$user_timezone timezone of the user, defined in his prefs $GLOBALS['egw_info']['user']['preferences']['common']['tz']
|
||||||
|
* 2. Api\DateTime::$server_timezone timezone of the server, read via date_default_timezone_get()
|
||||||
|
*
|
||||||
|
* The class extends PHP5.2's DateTime object to:
|
||||||
|
* - format date and time according to format in user prefs ($type===true: date, $type===false: time, $type==='' date+time)
|
||||||
|
* - defaulting to a user timezone according to user prefs (not server timezone as DateTime!)
|
||||||
|
* - deal with integer unix timestamps and DB timestamps in server-time ($type: 'ts'='integer' or 'server' timestamp in servertime)
|
||||||
|
*
|
||||||
|
* There are two static methods for simple conversation between server and user time:
|
||||||
|
* - Api\DateTime::server2user($time,$type=null)
|
||||||
|
* - Api\DateTime::user2server($time,$type=null)
|
||||||
|
* (Replacing in 1.6 and previous used adding of tz_offset, which is only correct for current time)
|
||||||
|
*
|
||||||
|
* An other static method allows to format any time in several ways: Api\DateTime::to($time,$type) (exceed date($type,$time)).
|
||||||
|
*
|
||||||
|
* The constructor of Api\DateTime understand - in addition to DateTime - integer timestamps, array with values for
|
||||||
|
* keys: ('year', 'month', 'day') or 'full' plus 'hour', 'minute' and optional 'second' or a DateTime object as parameter.
|
||||||
|
* It defaults to user-time, not server time as DateTime!
|
||||||
|
*
|
||||||
|
* The constructor itself throws an Exception in that case (to be precise it does not handle the one thrown by DateTime constructor).
|
||||||
|
* Static methods server2user, user2server and to return NULL, if given time could not be parsed.

|
* EGroupware time and timezone handling class extending PHP's DateTime
|
||||||
*
|
*
|
||||||
* egw_time class knows 2 timezones:
|
* @deprecated use Api\DateTime
|
||||||
* 1. egw_time::$user_timezone timezone of the user, defined in his prefs $GLOBALS['egw_info']['user']['preferences']['common']['tz']
|
|
||||||
* 2. egw_time::$server_timezone timezone of the server, read via date_default_timezone_get()
|
|
||||||
*
|
|
||||||
* The class extends PHP5.2's DateTime object to:
|
|
||||||
* - format date and time according to format in user prefs ($type===true: date, $type===false: time, $type==='' date+time)
|
|
||||||
* - defaulting to a user timezone according to user prefs (not server timezone as DateTime!)
|
|
||||||
* - deal with integer unix timestamps and DB timestamps in server-time ($type: 'ts'='integer' or 'server' timestamp in servertime)
|
|
||||||
*
|
|
||||||
* There are two static methods for simple conversation between server and user time:
|
|
||||||
* - egw_time::server2user($time,$type=null)
|
|
||||||
* - egw_time::user2server($time,$type=null)
|
|
||||||
* (Replacing in 1.6 and previous used adding of tz_offset, which is only correct for current time)
|
|
||||||
*
|
|
||||||
* An other static method allows to format any time in several ways: egw_time::to($time,$type) (exceed date($type,$time)).
|
|
||||||
*
|
|
||||||
* The constructor of egw_time understand - in addition to DateTime - integer timestamps, array with values for
|
|
||||||
* keys: ('year', 'month', 'day') or 'full' plus 'hour', 'minute' and optional 'second' or a DateTime object as parameter.
|
|
||||||
* It defaults to user-time, not server time as DateTime!
|
|
||||||
*
|
|
||||||
* The constructor itself throws an Exception in that case (to be precise it does not handle the one thrown by DateTime constructor).
|
|
||||||
* Static methods server2user, user2server and to return NULL, if given time could not be parsed.
