Can anyone tell me how I can get a second clock on my desktop?

If you run the sidebar on the windows setup you should be able to have a second clock showing.

Now to have it show a different time zone as your systems clock would need a little investigation though I am sure you can find out anything you want

edit:

Yes you can select options on the clocks preferences and then set THAT time zone to whatever you want it to be

Your system time stays as the system time at your current set time zone

Just download a timzones PC clock. It allows you to set analog or digital. display one or many at once.

And Canberra, Australia is in it. Only uses a couple of megabytes.

Right click on the desktop and select gadgets. When gadget window opens, select clock and the clock will

be added to your desktop. Then pick 'options' and select Australia time.

you can go to wal mart and buy you a clock to set on your desk.then set it at whatever time you desire.
