My question is what happens to a server that is actually at
15:00 and is 14:00.
For example, the case with oracle when I say that has to go
to the past?
What happens to the logs if they suddenly tell you that you
have to go to the past?
Oracle won't have a problem in terms of redo log generation,
or recoverability, because it uses an internal number (SCN) as
its "time". SCN always goes up.
It will have a problem with jobs you set up. For instance, it
may run twice simply because some time after it ran at 14:00,
the time becomes 14:00 again. So the jobs must be checked one
