Time On Time 
Corrected time is calculated as follows: Corrected time = ToT * Elapsed time With TimeOnTime (ToT) scoring, the time
allowance will increase progressively through the duration of the
race. Course distance has no effect on the results and need not
be measured. Corrected time will depend only on the elapsed time,
and the difference between boats may be seen in seconds depending of
the duration of the races. The longer the race in time, the larger
the handicap.

How is it calculated? 

Coastal/Long Distance Time on Time scoring coefficient is calculated as:  
600 / Coastal/Long Distance ToD  
Windward/Leeward Time on Time scoring coefficient is calculated as:  
675 / Windward/Leeward ToD  
Double handed coefficient is calculated with crew weight of 170 kg, while nonspinnaker rating is calculated for boat's performance without spinnaker. Double handed and Nonspinnaker ratings are given for both OSN (Offshore Time on Distance) and GPH calculations.
