Time zones

data TimeZone

A TimeZone is a whole number of minutes offset from UTC, together with a name and a "just for summer" flag.

Constructors

TimeZone

Fields

• timeZoneMinutes :: Int

  The number of minutes offset from UTC. Positive means local time will be later in the day than UTC.

• timeZoneSummerOnly :: Bool

  Is this time zone just persisting for the summer?

• timeZoneName :: String

  The name of the zone, typically a three- or four-letter acronym.

Time of day

data TimeOfDay

Time of day as represented in hour, minute and second (with picoseconds), typically used to express local time of day.

Constructors

TimeOfDay

Fields

• todHour :: Int

  range 0 - 23

• todMin :: Int

  range 0 - 59

• todSec :: Pico

  Note that 0 <= todSec < 61, accomodating leap seconds. Any local minute may have a leap second, since leap seconds happen in all zones simultaneously

Local Time

data LocalTime

A simple day and time aggregate, where the day is of the specified parameter, and the time is a TimeOfDay. Conversion of this (as local civil time) to UTC depends on the time zone. Conversion of this (as local mean time) to UT1 depends on the longitude.
