Adding Time

 
If I have a full date time string and I want to add two hours to that to come up with a new date time string, is it possible to do simple arithmatic, or must I parse, convert, add, reconvert? An example would be helpful. Thanks.
 

string TimePlus = TimeToStr((StrToTime("2008.2.8 12:00")+2*60*60), TIME_DATE|TIME_MINUTES);

 
phy:

string TimePlus = TimeToStr((StrToTime("2008.2.8 12:00")+2*60*60), TIME_DATE|TIME_MINUTES);


Thank you so very much!
