10 Section 3: Time of Day Clock
3 Time of Day Clock
The HERMIT 2000 maintains an internal, battery powered, time of
day clock. The clock remains operational when the instrument sleeps,
keeping track of the month, day of the month, and the time of day in
hours, minutes, and seconds. The clock is used to record the start
date and time of a test, and may be used to program delayed start
operations.
Time is kept in the 24-hour, or military, format, where 0 hours is
midnight. A time of 11:00 indicates 11 A.M. and a time of 23:00
indicates 11 P.M. The clock runs on a four-year cycle and does not
keep track of leap years.
