| Instances | |
|
|
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out of date in six months.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.
