Because I took Mordechai Abzug's API, I wrote a "date_string" method. I
just added an optional parameter: a string containing such things as
"%y", "%d" etc. So, my enhanced "date_string" method actually *is*
strftime with another name.
I could do this because the French_Rev calendar has concepts that
are similar to the Gregorian calendar it was meant to replace.
So, instead of a week number we have a d�cade number, instead
of a day of week (Mon, Tue...) we have a day of d�cade (Pri, Duo...).
But a Discordian and a Mayan would tell you different things...
By the way, answering another of your messages:
> Who needs %E* and %O* modifiers?
I need them. The traditional way to write a FR year is to use Roman
numerals. So, while %Y gives you the Indian-Arabian numerals (2003),
%EY gives you the Roman numerals (MMIII). At the same time, while
%j gives you the 1..366 number of a day, %Ej gives you the designation
of the day (which was meant to replace the saint of the day).
Example, from my .profile:
print $day->date_string("Today is %A %d %B %EY, %Ej%n");
gave me a few minutes ago:
Today is Sextidi 26 Niv�se CCXI, jour de l'�tain
