In both of the following examples, no business calendar is set for the session, so the query uses the system-defined business calendar Teradata.

The following query gives the day number of the month as 31 instead of 1 because the input is converted to UTC 2009-12-31 19:00:00.

SET TIME ZONE INTERVAL ‘05:00’ HOUR TO MINUTE;
SELECT DAYNUMBER_OF_MONTH (TIMESTAMP‘2010-01-01 00:00:00’);

The following query gives the day number of the month as 31 instead of 1 because the input is converted to UTC 2009-12-31 21:00:00.

SEL DAYNUMBER_OF_MONTH (TIMESTAMP’2010-01-01 00:00:00+03:00’);
