Hi cano,

DB2 only has 1 storage format for a time.  There are numerous display formats, but only 1 internal time format.

Using a 24 hour display format, times can be from 00:00:00 to 23:59:59.  At 24:00:00 the time rolls to 00:00:00 and the date (if it's a datetime object) advances 1 day.

If you're not seeing the time in the format that you expect, the issue is in the function call, or possibly the ODBC/JDBC driver.  It is not a database issue.
