Maybe I'm dense but shouldn't the clock be:

H: 0.01667
M: 1
S: 60

Yep, I'm a dumb, realized after a cup of coffee. Confirmed by the reply below.

Yes, you're dense lol. The speeds are correct: the second hand that does one full Revolution Per Minute, the minute hand does one full Revolution Per Hour and the hour hand does one Revolution Per 12 Hours.
