Command settings for RTC on linux

Beaglebone Black RTC



This is the command I use to setup my Beaglebone with RTC DS133833.

Set Date and Time manually:

date --set 2015-01-23
date --set 21:08:00

Change region/timezone:

dpkg-reconfigure tzdata

Read RTC date time value:

hwclock -r -f /dev/rtc1

Write date time value to RTC:

hwclock -w -f /dev/rtc1

another command is

hwclock -s -f /dev/rtc1

To store date time in CMOS(Non-volatile memory):

hwclock --systohc
