The time of day contains the current year, month, day of the week, day of the month, hour, minute, and second. The time-of-day MO monitors the time-of-day clock, and raises an alarm if the time-of-day clock is not set or cannot be read by the software. If the time-of-day clock is not set or cannot be read by the software, many features such as Time-of-Day Routing, CDR, ISDN Call-by-Call, and duplication, are inoperative or incorrect. Use set time to set the time-of-day clock when the system is initially powered up.
