Timezones

Every Supabase database is set to UTC timezone by default. We strongly recommend keeping it this way, even if your users are in a different location. This is because it makes it much easier to calculate differences between timezones if you adopt the mental model that "everything in my database is in UTC time".

Change timezone#

alter database postgres
set timezone to 'America/New_York';

Full list of timezones#

Get a full list of timezones supported by your database. This will return the following columns:

name: Time zone name
abbrev: Time zone abbreviation
utc_offset: Offset from UTC (positive means east of Greenwich)
is_dst: True if currently observing daylight savings

select name, abbrev, utc_offset, is_dst
from pg_timezone_names()
order by name;

Search for a specific timezone#

Use ilike (case insensitive search) to find specific timezones.

select *
from pg_timezone_names()
where name ilike '%york%';
