Yup. RTFCVSL :)

It is a result of fixing the date/time math across daylight savings time
boundaries. You will find that there is no longer an artifical one hour
offset in results when you add days, months, or years to a date or
timestamp.

I looked fairly carefully in the regression results before committing
the changes, but another pair of eyes always helps so let me know if you
notice anything funny...

I did, but the log didn't say anything about unfixed regression test
cases.  If you're going to leave some platform-specific comparison
files un-updated, I think it'd be polite to warn people about that
explicitly... probably on pghackers, not just committers...

I have updated horology-no-DST-before-1970.out, but that still leaves
us needing updates for horology-1947-PDT.out and
horology-solaris-1947.out.

*sigh*

I'll probably always leave some platform-specific comparison files
unupdated, and I would expect others to have to do that also. I
apparently did not meet your expectations on this, but it is quite in
line with our accepted practices.

Sorry for the heart stoppage when you saw your regression tests suddenly
failing...

I guess that we have already heard from someone on one of those, and the
others will come with time.
