RTFH. The HOUR() function ignores the setting of SET HOUR, and would return 0 at midnight, or 12 at noon. There is no time 24:00, there is a time 00:00; the range of times is 00:00 (midnight) - 23:59 (I left off seconds). Try the following:

tDateTimeTest = {^1999-01-01 24:00:00)  && errors out w/evaluated to an invalid value
tDateTimeTest = {^1999-01-01 00:00:00}  && midnight, January 1, 1999
? HOUR(tDateTimeTest)  && returns 0
