    Description

      When datetime argument is out of 31 bit timestamp representable domain or would be represented as a 0, CONVERT_TZ silently returns the argument unchanged. Documentation at the time of writing does not mention such behavior.

      Reproduction

      Input

      SELECT      CONVERT_TZ('1970-01-01 00:00:00', '+00:00', @@session.time_zone) AS ``,
      		 
                  CONVERT_TZ('1970-01-01 00:00:01', '+00:00', @@session.time_zone) AS ``,
      		 
                  CONVERT_TZ('2038-01-19 03:14:07', '+00:00', @@session.time_zone) AS ``,
      		 
                  CONVERT_TZ('2038-01-19 03:14:08', '+00:00', @@session.time_zone) AS ``

      Result

      ""	""	""	""
      		 
      1970-01-01 00:00:00	1970-01-01 03:00:01	2038-01-19 05:14:07	2038-01-19 03:14:08
