Methods

rnf :: AbsoluteTime -> () #

taiEpoch :: AbsoluteTime #

The epoch of TAI, which is 1858-11-17 00:00:00 TAI.

addAbsoluteTime :: DiffTime -> AbsoluteTime -> AbsoluteTime #

addAbsoluteTime a b = a + b

diffAbsoluteTime :: AbsoluteTime -> AbsoluteTime -> DiffTime #

diffAbsoluteTime a b = a - b

leap-second map type

type LeapSecondMap = Day -> Maybe Int #

TAI - UTC during this day. No table is provided, as any program compiled with it would become out of date in six months.

conversion between UTC and TAI with map

taiClock :: Maybe (DiffTime, IO AbsoluteTime) #

TAI clock, if it exists. Note that it is unlikely to be set correctly, without due care and attention.
