## How to deal with date and time in PostgreSQL?
|
|
- use `datetime` datatype without timezone (datetime with timezone is using offset, which doesn't work well with DST)
|
|
- store datetime in UTC
|
|
- add timezone information separately, use `Full time zone name` (human friendly)
|
|
- use `ISO 8601` format, which is human friendly to read and supported by every library
|
|
