Set Date Time in Linux

I need to adjust the date and time in linux quite often and sometimes its a pain to google the correct procedure of hardware clock and system clock. So here it is.

This will change both your system clock and hardware clock together
sudo date -s "7 JUN 2011 12:44:00"; sudo hwclock --systohc

1. Show System Clock date
2. Show Hardware Clock sudo hwclock --show
3. Change System Clock sudo date -s "2 OCT 2006 18:00:00"
4. Set Hardware Clock from System Clock sudo hwclock --systohc
5. Set System Clock from Hardware Clock sudo hwclock --hctosys
