Oops. I missed you need a time part only.

Why do you use "at time zone"  with a constant shift from GMT? If you
want to get your local zone, use just

SELECT current_time;

If you want to get current time in a specified part of the world, use
a region name:

postgres=# SELECT current_time AT TIME ZONE 'Asia/Tokyo', current_time
AT TIME ZONE 'US/Samoa';
      timezone      |      timezone
--------------------+--------------------
 20:10:57.924534+09 | 00:10:57.924534-11

Postgres uses set of rules when and how a shift from GMT changed (or
will change by knowledge at the current moment) for the concrete
region.
