+ help
+ Enables drivers for the Real-Time Clock battery-backed chips on
+ some products. The kernel reads the time when booting, and
+ the date can be set using ioctl(fd, RTC_SET_TIME, &rt) with rt a
+ rtc_time struct (see <file:include/asm-cris/rtc.h>) on the /dev/rtc
+ device. You can check the time with cat /proc/rtc, but
+ normal time reading should be done using libc function time and
+ friends.
