◆ get_name()

const String * Time_zone_utc::get_name ( ) const

overridevirtual

Because of constness of String returned by get_name() time zone name have to be already zeroended to be able to use String::ptr() instead of c_ptr().

Implements Time_zone.

long Time_zone_utc::get_timezone_offset ( ) const

inlineoverridevirtual

Returns the offset set for a Timezone offset.

This function has to be invoked ONLY when TZ_OFFSET is set.

Implements Time_zone.

tz_type Time_zone_utc::get_timezone_type ( ) const

inlineoverridevirtual

Returns the timezone type set.

Implements Time_zone.

void Time_zone_utc::gmt_sec_to_TIME	(	MYSQL_TIME *	tmp,
		my_time_t	t
	)		const

overridevirtual

Converts UTC epoch seconds to time in MYSQL_TIME representation.

Parameters

[out]	tmp	equivalent time point in MYSQL_TIME representation
[in]	t	number of seconds in UNIX epoch

Implements Time_zone.

my_time_t Time_zone_utc::TIME_to_gmt_sec	(	const MYSQL_TIME *	t,
		bool *	in_dst_time_gap
	)		const

overridevirtual

Converts local time in MYSQL_TIME representation to my_time_t (UTC seconds since Epoch) representation.

Returns 0 in case of error. Sets in_dst_time_gap to true if date provided falls into spring time-gap (or lefts it untouched otherwise).

Implements Time_zone.
