I saw your previous post and had intended on replying, but just hadn't 
gotten to it.  F$CVTIME() is not intended to do what you are trying to 
accomplish.
I'd suggest you look into using it to extract various components of 
time.  With the hour components, you could simply convert them to 
integers with F$INTEGER(hour_t1) and F$INTEGER(hour_t2) and then add 
those for a total of the hours.
