is_daylight_saving_time()

bool xtd::date_time::is_daylight_saving_time ( ) const

noexcept

Indicates whether this instance of xtd::date_time is within the daylight saving time range for the current time zone.

Returns

true if the value of the xtd::date_time::kind property is xtd::date_time_kind::local or xtd::date_time_kind::unspecified and the value of this instance ofxtd::date_time is within the daylight saving time range for the local time zone; false if xtd::date_time::kind is xtd::date_time_kind::utc.

Remarks

This method determines whether the current xtd::date_time value falls within the daylight saving time range of the local time zone, which is returned by the xtd::time_zone_info::local property. You can determine whether a time zone supports daylight saving time by retrieving the value of its xtd::time_zone_info::supports_daylight_saving_time property. For time zones that observe daylight saving time, you can determine when the transition to and from daylight saving time occurs by retrieving the xtd::time_zone_info::adjustment_rule array returned by the time zone's xtd::time_zone_info::get_adjustmen_rules property.

If the current xtd::date_time value represents either an ambiguous or an invalid time in the local time zone, the method returns false.
