If you "right click" on a blank part of the main screen you get a drop down box and one of the items is "gadgets". Click on that and you can then drag and drop the "clock" icon onto your screen. You can then position it where you like, personalise it by clicking on the spanner that appears next to it when you move your cursor over the clock. You can give it a name, change the time zone, style of clock, colour and opacity. I keep the opacity of mine fairly low so that it doesn't appear to be the main clock.
Hope that this helps - let me know!

Is there a toiletry you can no longer buy and miss?
