- I doubt it very much. The calendar application under X-windos does make the
- necessary correctionS.
-
- I was thinking about the problem the other way round. i.e. *whose*
- January 1st 1601 are MicroSoft talking about? The 100ns count for today will
- be different for Vatican City compared to London, for example.

-
- It is really not as simple as other european countries than England and
- Wales adopting the Gregorian calendar in 1582. Scotland to bring it a
- little closer to home changed in 1600. Russia changed in 1917. Alsaka
- didn't change until the 1800s (when it was purchased from Imperial Russia).
-
- Okay, okay, okay. I didn't say *all* other European countries. My Collins
- Dictionary didn't go into the finer details.
-
- Many states still do not use the Gregorian calendar and for religious
- reason will NEVER adopt it.
-
- All this causes considerable problems to anyone who is trying to write
- software that really MUST work with dates that far back in time and from
- all thoe places.
-
- > Yours facetiously
-
- You might have intended it so but it as I say a REAL problem to me as I am
- writing historical analysis software.
-
- You're right again. It *is* a problem to you, but as long a `nmake' can spot
- that I file has been changed in the last day or two, I'm not overly bothered
- about what Queen Elizabeth was up to.
