Command Group 2 — Real-Time Clock Control
Group 2 commands control the real-time clock, which maintains the time and date.
The user can set or display the time and date using Group 2 commands.
The real-time clock is supported by an internal lithium battery so that time and date
are preserved in case of power outage. The minimum life expectancy of the battery is
five years, and the battery has a typical life expectancy of 19 years.

Note: Enter the time exactly as shown with no spaces between characters. All entries
use decimal characters 0 through 9.
