Convert a TIME value to DAY-TIME interval, e.g. for extraction:
EXTRACT(DAY FROM x), EXTRACT(HOUR FROM x), etc.
Moves full days from ltime->hour to ltime->day.
Note, time_type is set to MYSQL_TIMESTAMP_NONE, to make sure that
the structure is not used for anything else other than extraction:
non-extraction TIME functions expect zero day value!
