Time zones
A TimeZone is a whole number of minutes offset from UTC, together with a name and a "just for summer" flag.

timeZoneOffsetString :: TimeZone -> StringSource
Text representing the offset of this timezone, such as "-0800" or "+0400" (like %z in formatTime)
timeZoneOffsetString' :: NumericPadOption -> TimeZone -> StringSource
Text representing the offset of this timezone, such as "-0800" or "+0400" (like %z in formatTime), with arbitrary padding
minutesToTimeZone :: Int -> TimeZoneSource
Create a nameless non-summer timezone for this number of minutes
hoursToTimeZone :: Int -> TimeZoneSource
Create a nameless non-summer timezone for this number of hours
getTimeZone :: UTCTime -> IO TimeZoneSource
Get the local time-zone for a given time (varying as per summertime adjustments)
getCurrentTimeZone :: IO TimeZoneSource
Get the current time-zone
Time of day
Time of day as represented in hour, minute and second (with picoseconds), typically used to express local time of day.
Constructors

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 -> TimeOfDaySource
Get a TimeOfDay given a time since midnight. Time more than 24h will be converted to leap-seconds.
timeOfDayToTime :: TimeOfDay -> DiffTimeSource
Find out how much time since midnight a given TimeOfDay is.
dayFractionToTimeOfDay :: Rational -> TimeOfDaySource
Get a TimeOfDay given the fraction of a day since midnight.
timeOfDayToDayFraction :: TimeOfDay -> RationalSource
Get the fraction of a day since midnight given a TimeOfDay.
Local Time
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.

utcToLocalTime :: TimeZone -> UTCTime -> LocalTimeSource
show a UTC time in a given time zone as a LocalTime
localTimeToUTC :: TimeZone -> LocalTime -> UTCTimeSource
find out what UTC time a given LocalTime in a given time zone is
ut1ToLocalTime :: Rational -> UniversalTime -> LocalTimeSource
1st arg is observation meridian in degrees, positive is East
localTimeToUT1 :: Rational -> LocalTime -> UniversalTimeSource
1st arg is observation meridian in degrees, positive is East
A local time together with a TimeZone.
