[Utah-astronomy] Fractional time zone value?

My newest mount control software allows for a fractional time zone entry in a hh:mm format. The default used to be in integer values, e.g. -7.0. Assuming a fractional time zone will increase the hand controller's pointing accuracy, any recommendations for or how to compute the factional hour zone minutes? - Kurt ____________________________________________________________________________________ Special deal for Yahoo! users & friends - No Cost.
