intlcal_set_time_zone
( IntlCalendar $cal
, mixed $timeZone
) : bool
Defines a new timezone for this calendar. The time represented by the object is preserved to the detriment of the field values.
参数
cal- The IntlCalendar resource.
timeZone- The new timezone to be used by this calendar. It can be specified in the following ways:
null, in which case the default timezone will be used, as specified in the ini setting date.timezone or through the function date_default_timezone_set() and as returned by date_default_timezone_get().- An IntlTimeZone, which will be used directly.
- A DateTimeZone. Its identifier will be extracted and an ICU timezone object will be created; the timezone will be backed by ICUʼs database, not PHPʼs.
- A string, which should be a valid ICU timezone identifier. See IntlTimeZone::createTimeZoneIDEnumeration(). Raw offsets such as
"GMT+08:30"are also accepted.
返回值
Returns true on success and false on failure.
