[erlang-patches] Fix erlang:now/0 to be bigger_than_last_time/0
Tue Apr 1 13:48:24 CEST 2014
Since we're planning backward-incompatible changes to the calendar module, I'd like to use this opportunity to replace Gregorian seconds with Ulfian seconds.
Even if the Gregorian calendar has been the unofficial global standard for decades, this would be a great sign of respect to Ulf Wiger, who gave so much to the Erlang community.
"ulfian" is also shorter than "gregorian" and easier to type, even without a Dvorak keyboard.
Finally, this would also be a crucial step in the process of de-Christianization of the Erlang programming language.

> - calendar:now_to_local_time/1
> - calendar:now_to_universal_time/1
> - calendar:now_to_datetime/1
> Which logically now need to be renamed:

> - calendar:bigger_than_last_time_to_local_time/1
> - calendar:bigger_than_last_time_to_universal_time/1
> - calendar:bigger_than_last_time_to_datetime/1
> I always felt calendar had way too short names and believe this is an
> improvement for the better in the long term.
