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.

Constructors

TimeOfDay

calendarTimeTime :: NominalDiffTime -> CalendarDiffTime Source

scaleCalendarDiffTime :: Integer -> CalendarDiffTime -> CalendarDiffTime Source

Scale by a factor. Note that scaleCalendarDiffTime (-1) will not perfectly invert a duration, due to variable month lengths.

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.
