I think this guy is exaggerating the reset procedure, with 20mins waiting.....
All you have to do is to drain all charges in the circuit.
For that Just disconnect the -ve terminal, then turn the key to ON position and apply front or rear brakes for some time. Connect the -ve terminal back and check if the clock is reset to 12:00.
I did it on my byke while fixing the aux lamp not intentionally, and I felt the difference in next ride.
I use to do the same in my car as other wise during summer and rainy/cold season, the throttle responce will be different or sluggish.
Applying breaks is to drain charges quickly through the tail lamps.
