This happens, twice yearly, when Daylight Savings Time commences and when Standard Time returns, and this involves an hour difference either way, and I've yet to experience any issues with Oracle. Yes, during the above-mentioned scenario you can duplicate an hour which could make it difficult to perform a PITR based upon clock time, but you still have the SCN as a reference point, and that doesn't change when the clock does.

I really see no issue here.
