The new Calendar Types in Elixir 1.3
summary
Elixir 1.3 introduces concrete structs for Date Time Time and NaiveDateTime with a calendar field to support alternate calendars and microsecond storage as a two element tuple showing microsecond value and significant precision. Conversions require explicit tagging so transforming a NaiveDateTime to UTC produces a proper DateTime. Integration examples use the calendar library plus tz data libraries and Ecto with Postgres composite types so timestamps keep zone info for correct comparisons.
