Time zones

data TimeZone Source #

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 Source #

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

TimeOfDay 24 0 0 is considered invalid for the purposes of makeTimeOfDayValid, as well as reading and parsing, but valid for ISO 8601 parsing in Data.Time.Format.ISO8601.

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 Source #
