Ancient Egyptians used the shadow clock (gnomon) to determine correct time. The Greeks used the water clock, or clepsydra. The first mechanical clock appeared in the fourteenth century. Then, in 1929 first electronic timepieces appeared. As time changes, so do the time-keeping devices. Now, in the beginning of the third millennium, the most precise time can be displayed only by the atomic clock. And thanks to the Internet and AlfaClock from www.alfasoftweb.com, you can have the atomic clock right on your desktop. At first glance, AlfaClock is a regular taskbar clock (sometimes called "tray clock"). But that is just your first impression. This tray clock combines multitude of cool features with stylish design. First, you can set AlfaClock to display time, date and day of the week simultaneously. Second, you can customize AlfaClock to announce this information periodically. And you can set an alarm - a very handy feature, if you frequently keep losing track of time, while using your computer. Atomic Clock Synchronization feature allows you to periodically connect to atomic clock time servers to make sure that your computer displays correct time and adjust it automatically, if necessary. Correct time may be critical to some computer users - for example, to professional eBay bidders, who make their final bids thirty seconds before the auction closes. AlfaClock has quite a few of extra features that other taskbar clocks don?t have. Like copy time/date to clipborad feature. Or a fully customizable pop-up calendar. Created to ISO8601 specifications, it allows you to change the first day of the week, highlight weekends and holidays. AlfaClock takes very little system resources and is fully compatible with all Windows versions - Windows 9x/ME/NT/2000/XP.
