Absolute intervals

data DiffTime #

This is a length of time, as measured by a clock. Conversion functions such as fromInteger and realToFrac will treat it as seconds. For example, (0.010 :: DiffTime) corresponds to 10 milliseconds.

It has a precision of one picosecond (= 10^-12 s). Enumeration functions will treat it as picoseconds.

UTC

UTC is time as measured by a clock, corrected to keep pace with the earth by adding or removing occasional seconds, known as "leap seconds". These corrections are not predictable and are announced with six month's notice. No table of these corrections is provided, as any program compiled with it would become out of date in six months.

If you don't care about leap seconds, use UTCTime and NominalDiffTime for your clock calculations, and you'll be fine.

data UTCTime #

This is the simplest representation of UTC. It consists of the day number, and a time offset from midnight. Note that if a day has a leap second added to it, it will have 86401 seconds.

Constructors

UTCTime
Fields utctDay :: Day the day utctDayTime :: DiffTime the time from midnight, 0 <= t < 86401s (because of leap-seconds)

data NominalDiffTime #

This is a length of time, as measured by UTC. It has a precision of one picosecond (10^-12 s).

Conversion functions such as fromInteger and realToFrac will treat it as seconds. For example, (0.010 :: NominalDiffTime) corresponds to 10 milliseconds.

Enumeration functions will treat it as picoseconds.

It ignores leap-seconds, so it's not necessarily a fixed amount of clock time. For instance, 23:00 UTC + 2 hours of NominalDiffTime = 01:00 UTC (+ 1 day), regardless of whether a leap-second intervened.
