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#
1alter database postgres 2set timezone to 'America/New_York';
