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
