Most likely.  Either the power failed in a bad way, upsetting the
hardware in your computer along the way, or your CMOS battery may be
running low, and this failure happened coincidentally.

If you often leave your computer switched off for many hours and your
clock is fine, then the battery is probably okay.

Unless you're running a CLI-only system, it seems like you've gone to an
awful amount of trouble to set the time and date, instead of just using
the system settings GUI that lets you set the clock.

The first thing that springs to mind is that you shouldn't have to
manually set the clock, I thought that Fedora set its clock from a time
server, by default, these days.

And the second thing that springs to mind regards the clock being way
off from what you expect:  Have you correctly set your computer's
timezone?  And since you've specified that you set the clock to UTC with
the -u flag, was 16:22 the actual UTC time at the time you set the
clock?

But personally, I'd just use the system settings GUI for the clock, pick
the timezone, and let the computer manage the clock setting for me over
the internet.  I dare say that just about all public NTP servers are
going to be more accurate than manually setting the time, and it
automatically takes care of any time errors that crop up from time to
time.
