So the capital "C" is the big spoiler here?

I thought I had an answer, but in my case the minutes and
seconds part seems to be slightly off (49 minutes instead of
50, and 38 seconds instead of 0):

*---------------- begin example ------------------
clear
drop _all
set obs 1
gen double time = clock("30dec1999 08:50:00", "DMYhms")
format time %tc
list
gen hour = hhC(time)
gen minute = mmC(time)
gen sec = ssC(time)
list
*----------------- end example --------------------

Maybe somebody else can explain where these differences
come from.
