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

Get the time since midnight for a given time of day.
dayFractionToTimeOfDay :: Rational > TimeOfDay #
Get the time of day given the fraction of a day since midnight.

data CalendarDiffTime #
Instances
scaleCalendarDiffTime :: Integer > CalendarDiffTime > CalendarDiffTime #
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.

Zoned Time
A local time together with a time zone.
There is no Eq
instance for ZonedTime

If you want to compare local times, use zonedTimeToLocalTime
.
If you want to compare absolute times, use zonedTimeToUTC
