timeZoneOffsetString :: TimeZone -> String Source

Text representing the offset of this timezone, such as "-0800" or "+0400" (like %z in formatTime).

timeZoneOffsetString' :: Maybe Char -> TimeZone -> String Source

Text representing the offset of this timezone, such as "-0800" or "+0400" (like %z in formatTime), with arbitrary padding.

minutesToTimeZone :: Int -> TimeZone Source

Create a nameless non-summer timezone for this number of minutes.

hoursToTimeZone :: Int -> TimeZone Source

Create a nameless non-summer timezone for this number of hours.

utc :: TimeZone Source

The UTC time zone.

getTimeZone :: UTCTime -> IO TimeZone Source

Get the local time-zone for a given time (varying as per summertime adjustments).

getCurrentTimeZone :: IO TimeZone Source

Get the current time-zone.

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

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

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.
