# 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

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.
