fromEpochTime' :: EpochTime -> UTCTime

type EpochTime = CTime

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)
