TimeZone representation class, along with time zone information data.
TimeZone representation class, along with time zone information data. The default timezone is set from the first valid timezone id found in one of the following places, in this order:
1) global $_DATE_TIMEZONE_DEFAULT
2) system environment variable PHP_TZ
3) system environment variable TZ
4) the result of date('T')
If no valid timezone id is found, the default timezone is set to 'UTC'. You may also manually set the default timezone by passing a valid id to Date_TimeZone::setDefault().
This class includes time zone data (from zoneinfo) in the form of a global array, $_DATE_TIMEZONE_DATA.
Located in /maintenance/libraries/pear/Date/TimeZone.php (line 48)
System Default Time Zone
DST Long Name of this time zone
DST Short Name of this timezone
true if this time zone observes daylight savings time
Time Zone ID of this time zone
Long Name of this time zone (ie Central Standard Time)
offset, in milliseconds, of this timezone
Short Name of this time zone (ie CST)
Constructor
Creates a new Date::TimeZone object, representing the time zone specified in $id. If the supplied ID is invalid, the created time zone is UTC.
Returns the list of valid time zone id strings
Returns the list of valid time zone id strings
Return a TimeZone object representing the system default time zone
Return a TimeZone object representing the system default time zone, which is initialized during the loading of TimeZone.php.
Returns the DST long name for this time zone
Returns the DST long name for this time zone, i.e. "Central Daylight Time"
Get the DST offset for this time zone
Returns the DST offset of this time zone, in milliseconds, if the zone observes DST, zero otherwise. Currently the DST offset is hard-coded to one hour.
Returns the DST short name for this time zone
Returns the DST short name for this time zone, i.e. "CDT"
Returns the id for this time zone
Returns the time zone id for this time zone, i.e. "America/Chicago"
Returns the long name for this time zone
Returns the long name for this time zone, i.e. "Central Standard Time"
Get the DST-corrected offset to UTC for the given date
Attempts to get the offset to UTC for a given date/time, taking into account daylight savings time, if the time zone observes it and if it is in effect. Please see the WARNINGS on Date::TimeZone::inDaylightTime().
Returns the raw (non-DST-corrected) offset from UTC/GMT for this time zone
Returns the raw (non-DST-corrected) offset from UTC/GMT for this time zone
Returns the short name for this time zone
Returns the short name for this time zone, i.e. "CST"
Returns true if this zone observes daylight savings time
Returns true if this zone observes daylight savings time
Is the given date/time in DST for this time zone
Attempts to determine if a given Date object represents a date/time that is in DST for this time zone. WARNINGS: this basically attempts to "trick" the system into telling us if we're in DST for a given time zone. This uses putenv() which may not work in safe mode, and relies on unix time which is only valid for dates from 1970 to ~2038. This relies on the underlying OS calls, so it may not work on Windows or on a system where zoneinfo is not installed or configured properly.
Is this time zone equal to another
Tests to see if this time zone is equal (ids match) to a given Date_TimeZone object.
Is this time zone equivalent to another
Tests to see if this time zone is equivalent to a given time zone object. Equivalence in this context is defined by the two time zones having an equal raw offset and an equal setting of "hasdst". This is not true equivalence, as the two time zones may have different rules for the observance of DST, but this implementation does not know DST rules.
Tests if given id is represented in the $_DATE_TIMEZONE_DATA time zone data
