The files are small (each will fit in a single fs block, for whatever
your favourite fs is), but the header line makes each one unique
anyway, so there's no saving in disk space for, say, venti.

It just seems odd that that GMT wasn't the obvious base for these
values.  Having spent a couple of years living inside the caldav mess,
I have an intense loathing of DST to begin with ...

But simplicity would seem to trump here, no?  Fixing ctime.c to deal
with GMT is trivial, vs.  trying to screw your head around which
(non-)DST timezone you're referencing as you walk though those files?

Is it Friday?  I need a pint of Old Peculiar.  Ooooh -- tomorrow is
April 1.  Let's punt this conversation for 24 hours.  (Or is that 23?
:-))
