DATE
(Access Level 1 or 2)
DATE displays the date stored by the internal calendar/clock. Type DATE
<ENTER> to read the date; DATE mm/dd/yy <ENTER> to enter a new
date. Since the clock is synchronized with the relay clock approximately every
five seconds, changing the date with this command is ineffective if the

SEL-DTA2 to benefit from the IRIG-B time code used by the target relay.
When the power is first turned on, the date is 1/1/91.
