Our AM335X customer Board is working without RTC
The Date will be fixed on 25 June 2013 when restart

Beaglebone Black uses RTC, but no battery
The Date also will be fixed on 25 June 2013 when restart

1.how to calculate the time without RTC in Linux??(If the power is stable)

2.If the power is stable, with or without RTC, the time difference between large quantities?

Hi Justin,

Without RTC, there is no way to keep track of time when your system is not running. Please refer to the following link for more information on how Linux keeps track of time: http://www.tldp.org/HOWTO/Clock-2.html

Best regards,
Miroslav
