But I believe that it would be a mistake to begin conversions of
programs to 64-bit mode for the next couple of years (except in
special circumstances). After that...
With 64 bit numbers available, I propose a new time standard, based
around 64-bit floats. We need a SMALL floating number (16 bits?) to
specify the millennium, and a large floating number (64 bits) to
specify the time. (0 = center of the millennium, +- 1 = +- 500
years, etc.). Current Millennium = 2 (years 2,000->2,999, CE). (I
allow for a year 0 before the year 1, if you wish to print that out
as 1 BC, that's merely a formatting issue.)
This would let us be as accurate as we have data available almost
all the time (i.e, creation of universe to end of universe [note:
the millennium was a floating point number]).
