Hi, It's look like bug in to_timestamp() function when format string has more whitespaces compare to input string, see below:
Ex.1: Two white spaces before HH24 whereas one before input time string postgres=# SELECT TO_TIMESTAMP('2016-06-13 15:43:36', 'YYYY/MM/DD HH24:MI:SS'); to_timestamp ------------------------ 2016-06-13 05:43:36-07 <— incorrect time (1 row) Ex.2: One whitespace before YYYY format string postgres=# SELECT TO_TIMESTAMP('2016/06/13 15:43:36', ' YYYY/MM/DD HH24:MI:SS'); to_timestamp ------------------------------ 0016-06-13 15:43:36-07:52:58 <— incorrect year (1 row) If there are one or more consecutive whitespace in the format, we should skip those as long as we could get an actual field. Thoughts? Thanks & Regards, Amul Sul -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
