Well, not quite, unless you're using a VERY non-ANSI-Standard version
of Rexx. :-)
Say Date('U',0,'B') --> 01/01/01
But you're right about the "C for Century"; it was always better to
think of it as the Roman numeral for 100. It still suffered from the
same boundary issues as the old Julian date, just not as frequently.
The fact is, Date('C') is not even legal at Rexx Language Level 4.00
(much less ANSI Standard) which has been around for quite a while now.
So the best option is to simply forget about the Date('C') option in
the first place and use Date('B') instead. If you have existing code
that you need to convert, you can establish the Date('C') epoch as a
constant (now 730119) offset to the Date('B') value.

It is right with the DATE(B) function - 01/01/1001.
All the technicalities aside, forget about the word "Century" and view
the letter "C" as an abstraction for the described function. Then,
everything is consistent, even if technically incorrect.

tyvm, Chip, for the explanation. So this century really began in
Jan 1, 2001, not 2000. Interesting.

Technically, the first year of each century is cc01, not cc00.
