easy solution for adding and subtracting time -

I have two combo boxes. In each combo box the user can select a time. It basically is for a user to select what time he wants to run a certain train pattern. So lets say in the one combo box, he selects 8:00 and in the next he selects 12:00. What i need to do is find the difference and display how many hours the pattern is run. In this case it is 4 hours if it is 8:00 AM to 12:00PM and 16 hours if it is 8:00 AM to 12:00 AM. You see the mess you can get into. But, does vb have some time format that would make this easy to do, that would automatically do time subtraction and addition. Any suggestions would be greatly appreciated.

Thanks,

Jeff
