F8 - Continuous Time Once-per-Second

This function is available through the command line interface only - it is not available through the keypad.
F8 generates time-of-year information (e.g., 199:10:41:08) once-per-second over the XLi's command
line interface (available from the serial or network ports). The format and type of time can be modified
using F2, F11, and F69.
The command line (standard out) outputs the <CR> character at the end of the time-of-year string at the
1 PPS mark, +/- 1 millisecond.
If F8 is used following startup, while the XLi is acquiring a reference source, F8's displays time-of-year
