RTC configuration
SYSFS INTERFACE ---

The sysfs interface under /sys/class/rtc/rtcN provides access to various rtc attributes without requiring the use of ioctls. All dates and times are in the RTC's timezone, rather than in system time.

date: 	   	 RTC-provided date hctosys:  	 1 if the RTC provided the system time at boot via the CONFIG_RTC_HCTOSYS kernel option, 0 otherwise max_user_freq:	 The maximum interrupt rate an unprivileged user may request from this RTC. name:		 The name of the RTC corresponding to this sysfs directory since_epoch:	 The number of seconds since the epoch according to the RTC time:		 RTC-provided time wakealarm:	 The time at which the clock will generate a system wakeup event. This is a one shot wakeup event, so must be reset after wake if a daily wakeup is required. Format is seconds since the epoch by default, or if there's a leading +, seconds in the future, or if there is a leading +=, seconds ahead of the current alarm.
