How do I convert a string which is actually a date with timezone to a timestamp in Presto?

问题

Example : 2017-12-24 23:59:59.000 PST

This does not work

select date_parse('2017-12-24 23:59:59.000 PST','%Y-%m-%d %T.%f %x')

Sure I can truncate the TZ which will solve

select date_parse(substr('2017-12-24 23:59:59.000 PST',1,23),'%Y-%m-%d %T.%f')

Is there a way to do this without truncating the TZ ?

回答1:

date_parse doesn't seem to support time zones, use parse_datetime instead:

presto> select parse_datetime('2017-12-24 23:59:59.000 PST', 'YYYY-MM-dd HH:mm:ss.SSS z');
                    _col0
