xotl.tools.future.datetime
This module extends the standard library's datetime. You may use it as a drop-in replacement in many cases.
Avoid importing * from this module since could be different in Python 2.7 and Python 3.3.
In Pytnon versions <= 3 date format fails for several dates, for example date(1800, 1, 1).strftime("%Y"). So, classes ~datetime.date and ~datetime.datetime are redefined if that case.
This problem could be solved by redefining the strftime function in the time module, because it is used for all strftime methods; but (WTF), Python double checks the year (in each method and then again in time.strftime function).

EmptyTimeSpan
The empty time span. It's not an instance of TimeSpan but engage set-like operations: union, intersection, etc.
No date is a member of the empty time span. The empty time span is a proper subset of any time span. It's only a superset of itself. It's not a proper superset of any other time span nor itself.
This instance is a singleton.
