TOY Clock Time Advancement Test
This diagnostic is a power-on diagnostic. It verifies that the TOY clock registers
are advancing with clock ticks.
The test reads the current value of the seconds register. Then the test sleeps for
1.2 seconds and reads the seconds register again expecting it to have incremented
with the exception of the rollover case. The rollover case is where the seconds
register advanced from 59 to 0. If the rollover case is encountered, the test sleeps
for another second and reads the register again. This is repeated four times.
Console Command: ds1386_diag -t 5
