I think some further investigation is in order. Is the clock electric or battery operated? This problem does sometimes occur with battery operated clocks as the battery gets weaker. Sorry if you already checked this out but can’t always assume and it is always good to verify the obvious. By the way is it digital, I was assuming it was the old mechanical style, meaning gears with big and little hand etc, is it? Some times the older clocks may show similar problems. If it is a mechanical type clock is your qigong practice by any chance between lets say 6 am and 12?
If Shr33m’s suggestion doesn’t yield any results then how about putting another clock in its place to see if it is you or the clock or something else in the same spot. If you had another clock of the same time it would be beneficial to exchange them to see if the problem is still there.
Some rambling from the analytical realm.
Let us know what happens?
