10.12 Time and Date Setting
There is no Real Time Chip (RTC) chip in the Prestige, so we have a software mechanism to get the current
time and date from an external server when you power up your Prestige. Menu 24.10 does just that – it
allows you to update the time and date settings of your Prestige. The real time is then displayed in the
Prestige error logs. If you do not choose a time service protocol that your timeserver will send when the
Prestige powers up you can enter the time manually but each time the system is booted, the time & date will
be reset to 2000/01/01 00:00:00.
10.12.1 How often does the Prestige update the time?
The Prestige updates the time in three instances:
i.
On leaving Menu 24.10 after making changes.
ii. When the Prestige boots up and there is a time server configured in Menu 24.9.
iii. The time is also updated at 24-hour intervals after booting.
