Usage

NOTE:

If using windows, you must set it's clock to UTC in addition to disabling windows "internet time update"

Control panel:
  Clock Language and Region:
    Date and Time:
      Internet tab:
        [ ] Synchronize with an internet time server

When updating your time, it is important to realize that
there are two dates: the software date, and the hardware clock.

timedatectl # control software clock
hwclock     # control hardware clock

## Install + Enable NTP
timedatectl set-ntp true

## sync the software clock with ntp
sudo ntpdate 0.ca.pool.ntp.org

# Check the hardware clock
hwclock

# If the hardware clock is different from the software clock, you can
# set the hardware clock to match the software clock with
hwclock --systohc

From this point onwards, the clock should boot with the correct time! If your clock is not the correct time after a reboot, you can troubleshoot what the problem is with the command timdatectl status. I have run into issues before where my timezone has not been set properly.
