> If the machine's local timezone involves DST, the UDFs return incorrect results.
> For example:
> {code}
> select to_utc_timestamp('2005-04-03 02:01:00','UTC');
> {code}
> returns {{2005-04-03 03:01:00}}. Correct result should be {{2005-04-03 02:01:00}}.
> {code}
> select to_utc_timestamp('2005-04-03 10:01:00','Asia/Shanghai');
> {code}
> returns {{2005-04-03 03:01:00}}. Correct result should be {{2005-04-03 02:01:00}}.
