The GMTTIME data type is similar to the TIME data type, except that its values are interpreted as values in Greenwich Mean Time.
DECLARE MyGetGmttime GMTTIME;
SET MyGetGmttime = GMTTIME '12:00:00';
The PutTime reported by WebSphere® MQ on z/OS® and other times or timestamps can be inconsistent if the CVT field is not set correctly.
