timeToDaysAndTimeOfDay :: NominalDiffTime -> (Integer, TimeOfDay) Source #
Convert a period of time into a count of days and a time of day since midnight. The time of day will never have a leap second.
daysAndTimeOfDayToTime :: Integer -> TimeOfDay -> NominalDiffTime Source #
Convert a count of days and a time of day since midnight into a period of time.
utcToLocalTimeOfDay :: TimeZone -> TimeOfDay -> (Integer, TimeOfDay) Source #
Convert a time of day in UTC to a time of day in some timezone, together with a day adjustment.
localToUTCTimeOfDay :: TimeZone -> TimeOfDay -> (Integer, TimeOfDay) Source #
Convert a time of day in some timezone to a time of day in UTC, together with a day adjustment.
timeToTimeOfDay :: DiffTime -> TimeOfDay Source #
Get the time of day given a time since midnight. Time more than 24h will be converted to leap-seconds.
pastMidnight :: DiffTime -> TimeOfDay Source #
Same as timeToTimeOfDay
.
timeOfDayToTime :: TimeOfDay -> DiffTime Source #
Get the time since midnight for a given time of day.
sinceMidnight :: TimeOfDay -> DiffTime Source #
Same as timeOfDayToTime
.
dayFractionToTimeOfDay :: Rational -> TimeOfDay Source #
Get the time of day given the fraction of a day since midnight.
timeOfDayToDayFraction :: TimeOfDay -> Rational Source #
Get the fraction of a day since midnight given a time of day.
Calendar Duration
data CalendarDiffTime Source #
Instances
scaleCalendarDiffTime :: Integer -> CalendarDiffTime -> CalendarDiffTime Source #
Scale by a factor. Note that scaleCalendarDiffTime (-1)
will not perfectly invert a duration, due to variable month lengths.
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.
