Forcing a reset is NOT always worth it. It is worth it if you time it well and take advantage of it after you complete the reset. The key value in a reset is that it makes it possible to kill some opponents 4 times instead of the non-reset limit of 3 times/war.
That said, the timers do NOT bump forward. If they did it would eliminate the value of the reset.
