--------------------------------------
Hi [~0x62ash] this could be caused by an outdated java runtime. What java
versions are you running in both client and server?

> Incorrect time zones for convert_tz()
> -------------------------------------
>
> Key: PHOENIX-5567
> URL: https://issues.apache.org/jira/browse/PHOENIX-5567
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.14.2
> Reporter: Alex Batyrshin
> Priority: Major
>
> 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' |
> +--------------------------+---------------------------------+
> | 2019-01-01 00:00:00.000 | 2019-01-01 03:00:00.000 |
