"Official" times are started on first movement -- any movement, even if it it not forward. Some guys move their off hand first, or rock backward. That is why "official" times are typically higher, very rarely lower.
I'm not sure I like the electronic timer. The guy who's able to push off with both hand and foot at the same time gets the "extra" advantage that is already built in with the good stance/get off in the first place.
