[cvsnt] -D option, for files before 2000.01.01 finds nothing?

[Michael KENNY]

Hi all,

Does CVSNT have a restriction on pre year 2000 files?

I'm in the process of transfering older projects into CVSNT.
I have the files in CVS and can see them fine e.g. in eclipse
resource history going back to dates like 1998.06.06 etc.

Going back in time doing something like
cvs diff -l -D 2006.02.04 works as expected
so does
cvs diff -l -D 2000.01.02

but from

cvs diff -l -D 2000.01.01

I get no more resuts, instead:
cvs server: Diffing .
cvs server: no revision for date 99.12.31.23.00.00 in file XXXXXX

As soon as I go back to 2000.01.02 I get the expected diff result
again - (between rev2 and rev12 -- rev2 being the 1998.06.06 file)

I get similar behaviour with cvs -n co -D <dates here>
as soon as I enter 2000.01.01 the files before this date appear
unknown...the 
U <file path etc> line for the file in question is no longer listed
