I'd think the result'd be 09:51:16, why 04:51:16?

Timezone issues. Try formatting in the neutral GMT timezone:

clock format [expr {([clock scan 09:51:16] - [clock scan 00:00:00])}]
-format "%H:%M:%S" -gmt 1

That only hides the problem for a little bit.
It'll still be bogus is the value is more than 24 hours.
