> Looks like convert_tz() uses incorrect (old) timezone information for 'Europe/Moscow'.
> From October 2014 time zone in Moscow is *always*: UTC+03:00, but Phoenix convert summer/winter times to different offset.
> Test cast:
> {code:java}
> 0: jdbc:phoenix:10.73.67.148> select dt as as_is, convert_tz(dt, 'UTC', 'Europe/Moscow') from (select to_timestamp('2019-01-01') dt);
> +--------------------------+---------------------------------+
> |          AS_IS           | DATE '2019-01-01 03:00:00.000'  |
> +--------------------------+---------------------------------+
