Main system clock (Freelander 2)

The ICM contains the main system clock function. Other entertainment modules in the vehicle that require time function receive their data from the ICM.

The clock is available to any control module if it is connected to a connecting bus, such as the CAN buses or the MOST bus.

The display can show the time in a 12-hour format (AM and PM) or can be set to a 24-hour format. Accordingly, midnight is indicated as 12:00 AM or 00:00:00. When the power is turned on, the clock will default (if not otherwise set) to 12:00 PM or 00:00. Depending on the market, the clock defaults to either a 12-hour or 24-hour format.

The time is set via the ICM. If any of the data buses are currently disabled or in "sleep" mode, the ICM does not allow clock adjustment.
