Calendar
The Controller features a year 2000-compliant hardware real-time clock and
calendar circuit with a lithium power source. Accurate time keeping is
maintained during loss of main power.
To announce the time or date, you place special codes called Message Run-
Time Variables into messages. See page 4-35 for more information.
The clock and calendar circuit is accurate to ±1 minute per month. For
improved accuracy, commands are provided to manually or automatically
adjust the clock to compensate for drift.
