In Crystal 8.5, you should be able to 'bundle' them, something like
DateValue (datepart("yyyy", datadate),
datepart("m", datadate), datepart("d", datadate),
datepart("h", datatime), datepart("n", datatime))
This gives you year, month, day, hour and minute. You can then use 'DateDiff' to make comparisons, for hours it would be
DateDiff("h", @YourDate, otherdate)
