### Reference epoch
the reference epoch of the AaaaHorodatage class stored in _epoch_ class attribute
Default is 1900. Range: 0 <= _epoch_ <= 9999.
You can use _get_epoch_ or _set_epoch_ class methods to get or set it.
Please, be consistent with yourself! e.g., you must encode and decode the same timestamp with the same epoch; or the results will be incoherent. It's why this method is a class method.
Remember this: The only way to know what is the reference epoch of a time stamp, is to remember it.
