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,
