/**
  @file
  This service provides functions to convert between my_time_t and
  MYSQL_TIME taking into account the current value of the time_zone
  session variable.

The values of the my_time_t type are in Unix timestamp format,
  i.e. the number of seconds since "1970-01-01 00:00:00 UTC".

The values of the MYSQL_TIME type are in the current time zone,
  according to thd->variables.time_zone.

If the MYSQL_THD parameter is NULL, then global_system_variables.time_zone
  is used for conversion.
