I am writing an article of PostgreSQL 7.1 and have some questions.
I can get the millisecond part of a timestamp data using date_part.
test=# SELECT date_part('millisecond','2001/1/15 12:04:05.1234'::TIMESTAMP);date_part
----------- 123.4
(1 row)
However if I apply the function to a time data, I get a strange result.
test=# SELECT date_part('millisecond','12:04:05.1234'::time); date_part
------------------5123.39999999676
(1 row)
Any thought?
(This is current)
