timeZoneOffsetString :: TimeZone -> String Source #

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

timeZoneOffsetString' :: NumericPadOption -> 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

utcToLocalTimeOfDay :: TimeZone -> TimeOfDay -> (Integer, TimeOfDay) Source #

Convert a ToD in UTC to a ToD in some timezone, together with a day adjustment.

localToUTCTimeOfDay :: TimeZone -> TimeOfDay -> (Integer, TimeOfDay) Source #

Convert a ToD in some timezone to a ToD in UTC, together with a day adjustment.

timeToTimeOfDay :: DiffTime -> TimeOfDay Source #

Get a TimeOfDay given a time since midnight. Time more than 24h will be converted to leap-seconds.

timeOfDayToTime :: TimeOfDay -> DiffTime Source #

Find out how much time since midnight a given TimeOfDay is.

dayFractionToTimeOfDay :: Rational -> TimeOfDay Source #

Get a TimeOfDay given the fraction of a day since midnight.

timeOfDayToDayFraction :: TimeOfDay -> Rational Source #

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.
