We'll see differences between hardware clock and system clock

hwclock --show

Let's set the hardware clock to local time:

hwclock --set --date="2012-04-19 16:45:05" --localtime

If you want to set it to UTC time use:

hwclock --set --date="2011-04-19 20:45:05"  --utc                  (toronto is using EDT in summary, EST in winter)

Set the timezone

To set the timezone of your system clock do the following:

cp /usr/share/zoneinfo/America/La_Paz /etc/localtime
