Epoch

class Epoch epoch where Source #

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.

epochName, epochDiffToUnix

Methods

epochName :: epoch -> String Source #

The name of this epoch

epochDiffToUnix :: epoch -> Seconds Source #

number of seconds of difference with 1st January 1970.

a negative number means that this epoch start before the unix epoch.
