ClockOnTop allows you to add a digital clock to the top bar (known as the taskbar) of Windows Mobile. This is a feature that should really be there by default and this program is better than nothing although in reality, it's performance is hit and miss.
By default, it's in 24 hour format but if you want the 12-hour format, you need to place the extra LNK file in ZIP in the \Windows\Start Up folder.
Make sure to run the ClockOnTop application so that you replace the file that is placed in that folder. Then reset. You should see the 12-hour format and a foreign symbol of some kind.
However, you may experience some reliability problems with ClockOnTop. The clock often seems to disappear only to reappear randomly. Basically, it's not a good idea to rely on this as your only time telling device as you may be left stranded without the time on many occasions.
