The TIMETOL=nnnn parameter specifies the difference between the time-of-day (TOD) clocks of this node and any adjacent node at signon. JES2 checks this value when the adjacent node attempts to sign on to your NJE network. Any adjacent node whose value is above or below the TIMETOL value is rejected by JES2. Nodes that had signed on under an earlier TIMETOL value are not disconnected by this command.
