Initial parameters

DTWAT

DTWAT= ((Time step * (ITimeWindow -1)) / 8) = ((36 * (10-1)) / 8) = 40.5 days

First authentication

A new user has not yet successfully authenticated:

Used time window	= max (SyncWindow, ITimeWindow * time step)
	= max (21600 seconds, 360 seconds) = 21600 seconds = 600 time steps
	= +/- 300 time steps

Authentication before DTWAT

The user authenticates within 40.5 days after the last successful verification:

Authentication after DTWAT

The user authenticates between 40.5 days and 2695.5 days after the last successful verification.

Used time window

= Time step + (Days lapsed * 8)
