Nightime-R is a program to allow parents to set daily computer usage time limits. Each day has a separate 'Allowed Time', 'Sleep Time' and a 'Daily Limit'. Different times/limits can be set for each log-on user. When time limits have been reached the computer is put into sleep mode. A computer voice and visual warning gives a count-down at 15, 10, 5, 2 and 1 minute points. A large count-down time is shown on the screen backdrop.
