I never can keep track of which side of DST I'm on.
Confirming... yeah, you're right.  Still doesn't explain anything.

It isn't.  Entries contains 16:46 right now and it's 17:46 GMT.

Well, those are the same three culprits I was considering once someone
pointed me at CVS/Entries.

Okay, emacs appears to have the right mtime, although I have to have a
strange reading of the file-attributes doc in order to see it that
way:

 4. Last access time, as a list of two integers.
  First integer has high-order 16 bits of time, second has low 16 bits.

It's (17046 2788)

If that's really meant to be a 32-bit number and 17046 means 17:46,
there are some big gaps in numerical time. ;-)

A dialog box ;-)

Surely.

A little, but I'm afraid I'm still stuck (just a little further
forward than I was).

The latest information I can find about this is from 2003, and I've
been using Cygwin CVS through DST changes for years without incident.

Another prominently indexed thread from 2001 ends with:
http://groups-beta.google.com/group/gnu.cvs.help/msg/8fe939925748a068?hl=en
so I'm almost afraid to ask.
