mydb=# select to_timestamp('00000000 0300','yyyymmdd hh24mi');      to_timestamp
---------------------------0001-01-01 03:00:00+01 BC
(1 row)

Questionable, but probably valid.



mydb=# select to_timestamp('         0300','yyyymmdd hh24mi');     to_timestamp
------------------------0300-12-25 03:00:00+01
(1 row)

This puzzles me. Where is the 25th of december coming from?



mydb=# select to_timestamp('         030004','yyyymmdd hh24mi');     to_timestamp
------------------------0382-04-23 03:00:00+01

Same as above.


mydb=# select to_timestamp('         040004','yyyymmdd hh24mi');     to_timestamp
------------------------0509-10-10 04:00:00+01


I think all except the first one should raise a warning, isn't it? Where can I 
find the source code of this function?

Best regards,Mario Weilguni
