I don't think it's ever happened to me personally, but I've seen many such
reports from time to time. Most seem to come from the Roswell, NM area, but
other areas are affected.

Ok, more seriously, - yes others have seemingly found it changed and they do
not know how. The possibilities are myriad, from gremlins, to forgotten
actions, to accidental actions, to code that set it differently and then
didn't set it back, and of course, LGM could have done it - if you live near
Roswell.
