Why are you taking the difference between two constant times? That doesn't make much sense.
Are you trying to see if the variable is between the two constants?
Perhaps something like this?
'11:00't <= starttime <='19:00't

I am not clear with the query, but you can try the below code
data have;
input Starttime :time5. endtime :time5.;
if Starttime>='19:00't then afterhout='afterhour';
format Starttime endtime time5.;;
cards;
16:55 17:29
14:41 14:58
20:37 20:43
23:52 0:02
