Data.Hourglass.Epoch
Description
Epoch tracking
Synopsis
- newtype ElapsedSince epoch = ElapsedSince Seconds
- data ElapsedSinceP epoch = ElapsedSinceP !(ElapsedSince epoch) !NanoSeconds
- class Epoch epoch where
- epochName :: epoch -> String
- epochDiffToUnix :: epoch -> Seconds
- data UnixEpoch = UnixEpoch
- data WindowsEpoch = WindowsEpoch
computer time tracking with various epoch
newtype ElapsedSince epoch #
A number of seconds elapsed since an epoch.
Constructors
ElapsedSince Seconds |
Instances
data ElapsedSinceP epoch #
A number of seconds and nanoseconds elapsed since an epoch.

Epoch
epoch related.
We use the well known Unix epoch as the reference timezone for doing conversion between epochs.
Each methods of this typeclass should not use the actual value, but only get the information needed from the type itself.
Methods
epochName :: epoch -> String #
The name of this epoch
epochDiffToUnix :: epoch -> Seconds #
number of seconds of difference with 1st January 1970.
a negative number means that this epoch start before the unix epoch.
