Almost certainly due to daylight savings time in PST8PDT (it happened
today). As the doctor says, you'll feel better in a couple of days :)

This happens every year (actually, twice a year). But it would be
wrong to not test the yesterday/today/tomorrow feature at all...

I'm guessing that 2.8.x is not in wide-spread use. What platform are
you on? You could force -O0 for your platform, even just for that
directory, as long as you don't disable it for other platform/compiler
combinations.
