-    -d FILE	Device to use (default /dev/rtc)
-    -l	RTC uses local time
-    -m	Mode (--list-modes to see those supported by your kernel):
-    	  standby  S1: default              mem     S3: suspend to RAM
-    	  disk     S4: suspend to disk      off     S5: power off
-    	  disable  Cancel current alarm     freeze  stop processes/processors
-    	  no       just set wakeup time     on      just poll RTC for alarm
-    	  show     just show current alarm
-    -s SECS	Wake SECS seconds from now
-    -t UNIX	Wake UNIX seconds from epoch
-    -u	RTC uses UTC
-    -v	Verbose
