Furthermore, this is an Extremely Bad Idea:

gen clock_date2= Clock(clock_date, "YMDhms")

All variables which are to store intraday time information should be declared as double, as their precision relies on large integer values being retained as such.  Making them floats messes that up big time (groan), as the help and manual states.
