Real-Time Clock (RTC)

Real-Time Clock Linux has a rich API to support RTC functionality, so we will not be supplementing
(RTC)
x
or modifying that API. The M 800 series of terminals include VeriFone specific
RTC hardware required to keep the time accurate when the unit is turned off.
On power up, the operating system will automatically set the Linux (soft) RTC
x
from the M 800 series terminal RTC hardware.
The setRTC() function must be called immediately after any call that sets the
time/date of the Linux RTC or the updated time/date will be lost when the unit is
turned off.
