Kinda. That should be accompanied by a change in UTC offset,
indicating that time hasn't gone backwards, just the clock. Anything
that queries the clock in UTC shouldn't see it go backward. But if
there's a time server that's misconfigured, and it actually jumps time
backward, then yes, you could see NTP change the time back by an hour
once a year. It's wrong, but it certainly can happen.
