Calculating the average of two UTC times

Hi there,

I would like to calculate the average of two UTC times, start and end each with three variables (H:M:S).

Excel has a nice function which considers the special format: 

=AVERAGE(TIME(C2,D2,E2),TIME(F2,G2,H2))

I'd like to avoid the long way into Excel and back. Does AutoIT has a similar function I didn't find yet?

(X+Y)/2 is imprecise as hours and minutes consist of 60 not 100 entities.

Regards
