OK. However, doing that would cause the rearguard and main timestamps to 
disagree in UTC offset for a month or so. It'd be less intrusive to add 
a transition after the last transition, which I hope would also work 
around the problem (as it'd exhibit a similar pattern) but would cause 
the rearguard and main timestamps to disagree only with respect to the 
isdst flag for a day, which is less of a difference.

I installed the attached proposed patch to do that. Does it work for 
you? If not, perhaps we should revert all these workarounds, and go back 
to what we were doing in this area before commit
