19   This service provdes functions to convert between my_time_t and
20   MYSQL_TIME taking into account the current value of the time_zone
21   session variable.
22 
23   The values of the my_time_t type are in Unix timestamp format,
24   i.e. the number of seconds since "1970-01-01 00:00:00 UTC".
25 
26   The values of the MYSQL_TIME type are in the current time zone,
27   according to thd->variables.time_zone.
28 
29   If the MYSQL_THD parameter is NULL, then global_system_variables.time_zone
30   is used for conversion.
