Kevin,
The current RTC driver works with the existing MSP430 firmware
and takes care of this AM/PM anomalay. Loc will be in a position to
comment whether the new MSP430 firmware is available on the production
boards.
Current RTC driver will work with the new MSP430 firmware also.

Is the updated MSP430 firmware shipping on production boards? If so we
should switch to Dave's new driver.
