A common file found here is rtc which provides output from the driver for the system's Real Time Clock (RTC), the device that keeps the time while the system is switched off. Sample output from /proc/driver/rtc looks like the following:

rtc_time        : 16:21:00 
rtc_date        : 2004-08-31 
rtc_epoch       : 1900 
alarm           : 21:16:27 
DST_enable      : no 
BCD             : yes 
24hr            : yes 
square_wave     : no 
alarm_IRQ       : no 
update_IRQ      : no 
periodic_IRQ    : no 
periodic_freq   : 1024 
batt_status     : okay
