How does convert_tz works in mysql,while going through some mysql site on web I encountered this function,when I tried replicating it, it is giving me the null value. why isn't this working?. Following is the script
SELECT CONVERT_TZ('2004-01-01 12:00:00','GMT','MET');
this is the output shown on web for convert_tz(),
mysql> SELECT CONVERT_TZ('2004-01-01 12:00:00','GMT','MET');
+---------------------------------------------------------+
| CONVERT_TZ('2004-01-01 12:00:00','GMT','MET') |
+---------------------------------------------------------+
| 2004-01-01 13:00:00 |
