Data.Time.Clock.TAI
Description
TAI and leap-second tables for converting to UTC: most people won't need this module.
Synopsis
data AbsoluteTime
taiEpoch :: AbsoluteTime
addAbsoluteTime :: DiffTime -> AbsoluteTime -> AbsoluteTime
diffAbsoluteTime :: AbsoluteTime -> AbsoluteTime -> DiffTime
type LeapSecondTable = Day -> Integer
utcDayLength :: LeapSecondTable -> Day -> DiffTime
utcToTAITime :: LeapSecondTable -> UTCTime -> AbsoluteTime
taiToUTCTime :: LeapSecondTable -> AbsoluteTime -> UTCTime
parseTAIUTCDATFile :: String -> LeapSecondTable
Documentation
data AbsoluteTime
AbsoluteTime is TAI, time as measured by a clock.
Instances
Eq AbsoluteTime
Ord AbsoluteTime
Show 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
type LeapSecondTable = Day -> Integer
TAI - UTC during this day. No table is provided, as any program compiled with it would become out of date in six months.
utcDayLength :: LeapSecondTable -> Day -> DiffTime
utcToTAITime :: LeapSecondTable -> UTCTime -> AbsoluteTime
taiToUTCTime :: LeapSecondTable -> AbsoluteTime -> UTCTime
parseTAIUTCDATFile :: String -> LeapSecondTable
Parse the contents of a tai-utc.dat file. This does not do any kind of validation and will return a bad table for input not in the correct format.
