| 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. |
