Times to re-entrainment under the schedules presented in figure 1.

The number of days required to achieve re-entrainment (both complete and partial) are recorded for each of the seven schedules presented in figure 1. The number of days does not include the first day on which re-entrainment occurs (i.e. if re-entrainment occurs on the third day then the number of days required is two). This way if the subject starts out re-entrained the number of days required is zero. Complete re-entrainment is said to occur when CBTmin falls within approximately one hour of the exactly entrained time (the dotted line in figure 1). Partial re-entrainment is said to occur when CBTmin falls within the sleep/dark region of the destination time zone.
