On server - UTC
Local - Europe/Moscow
For example, from 1920 all right:
If run in DataGrip:
select '1900-01-01 15:11:10'::timestamp t1, '1900-01-01
15:11:10'::timestamp at time zone 'Europe/Moscow' as t2
1900-01-01 15:11:10.000000 1900-01-01 12:40:53.000000
select '1920-01-01 15:11:10'::timestamp t1, '1920-01-01
15:11:10'::timestamp at time zone 'Europe/Moscow' as t2
1920-01-01 15:11:10.000000 1920-01-01 12:11:10.000000
select '1900-01-01 15:11:10'::timestamp t1, '1900-01-01
15:11:10'::timestamp at time zone 'UTC-3' as t2
1900-01-01 15:11:10.000000 1900-01-01 12:11:10.000000
Thanks
