Time_zone_offset::Time_zone_offset ( long  tz_offset_arg)

Member Function Documentation

◆ get_name()

const String * Time_zone_offset::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.

◆ get_timezone_offset()

long Time_zone_offset::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.

◆ get_timezone_type()

tz_type Time_zone_offset::get_timezone_type ( ) const
inlineoverridevirtual

Returns the timezone type set.

Implements Time_zone.

◆ gmt_sec_to_TIME()

void Time_zone_offset::gmt_sec_to_TIME ( MYSQL_TIME tmp,
my_time_t  t 
) const
overridevirtual

Converts time in my_time_t representation to local time in broken down MYSQL_TIME representation.

Implements Time_zone.

◆ TIME_to_gmt_sec()

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

Converts time in time zone defined as a displacement from UTC from MYSQL_TIME representation to its my_time_t representation.

Parameters
tMYSQL_TIME structure with local time in broken-down representation.
[out]in_dst_time_gapPointer to bool which should be set to true if datetime value passed doesn't really exist (i.e. falls into spring time-gap) and is not touched otherwise. It is not really used in this class.
Returns
Corresponding my_time_t value or 0 for invalid datetime values.

Implements Time_zone.
