Hello all,

I recently opened a backup ".RData" file which contained (three) "time
variables" created in the session I had a few months ago.
Upon inspecting those variables I suddenly realized they all got an extra
hour to them.

So a variable like:
morning <- as.difftime("08:00:00")
That was defined a few months ago (and saved inside the .RData file) will
be:
print(morning)
Time difference of 9 hours


I have no clue how that might have happened.
The only reason I can think about was maybe somehow the change in "daylights
savings time" effected it - but I wasn't able to reproduce the problem by
changing my machine time (after saving the RData, closing R, changing
machine time, reopening R with the RData).

Any idea way this had happened?
