type Scalar NominalDiffTime = Rational

toMicroseconds :: NominalDiffTime -> Micros

Convert from NominalDiffTime to a 64-bit representation of microseconds.

fromMicroseconds :: Micros -> NominalDiffTime

Convert from a 64-bit representation of microseconds to NominalDiffTime.

toSeconds :: NominalDiffTime -> Decimal

Convert from NominalDiffTime to a Decimal representation of seconds.

fromSeconds :: Decimal -> NominalDiffTime

Convert from Decimal representation of seconds to NominalDiffTime.

The result is rounded using banker's method, i.e. remainders of 0.5 a rounded to the next even integer.

nominalDay :: NominalDiffTime

The nominal length of a day: precisely 86400 SI seconds.

UTCTime

newtype UTCTime

UTCTime with microseconds precision. Internally it is represented as 64-bit count nominal microseconds since MJD Epoch.

This implementation ignores leap seconds. Time differences are measured as nominal time, with a nominal day having exaxtly 24 * 60 * 60 SI seconds. As a consequence the difference between two dates as computed by this module is generally equal or smaller than what is actually measured by a clock.
