Re: MS Visual C++ daylight saving time bug

[David L. Martin]

Alex,

The MS Visual C++ daylight saving time bug probably only affected
my local build of WinCVS because I was not using Service
Pack 3 or higher.

I recompiled WinCVS using Visual Studio Service Pack 5, and the
particular problem I was seeing went away (that all files committed
since April 1, 2001 were always showing up as Modified).  A
subsequent update of these files fixed it.  

(I supposed I could have been patient and wait until April
9, 2001 for the problem to go away, but I wanted to be certain
it was the MS Visual C++ bug causing that problem).

I still find that for WinCVS on NT that after a daylight saving time
switch that I need to either cvs status, cvs update, or cvs -n update
my working area (basically, any operation that will rewrite the
CVS/Entries file) before the Modified file indication is cleared.  I did
not need to do this on Win 98.  This may be related to the way NTFS
handles file modification times after a daylight saving time transition,
as was previously noted in this thread.

Regards,
David Martin
