How would you like a state-of-the-art, fully customizable and elegant little international world time clock program for your Windows desktop? Look no further, you have come to the right place! Sharp World Clock is probably the most sophisticated and beautiful time zone clock program for the Windows desktop, perfectly designed for the demanding private and business user.

Sharp World Clock is not only a universal time zone clock with almost every function you can imagine, using the most sophisticated modern programming techniques - it can also help you to improve your geographical knowledge with Country Flags on its interface and the State Borders on its built-in World Map and is enjoyably, intuitively and easy to use. It's not just a tool - it's also a toy! This program is shareware and you can try it free with all its features and without any risk for a period of 15 days from the day of installation.

Thanks to the always up-to-date implementation of Daylight Saving (DST) rules (for every time zone, with web update), the program will always tell you the exact time in every location on earth. It also displays the precise Sunrise and Sunset time for each location and even the current Moon Phase as well as the date of the next full moon and new moon. There is a built-in Time Zone Converter / Calculator, a multiple Alarm Clock with 10 alarms: one-time, daily, every specific day of the week... and a Calendar with reminder plus Atomic (Internet) Time Synch, System Tray mode, a Click-Through-Mode and an Always-On-Top mode. A powerful and easy-to-use RSS/Atom Feed Reader with search function keeps you in touch with your favourite news feeds from the internet. Hide and show the program window with a simple mouse click at the tray icon or use a (customizable) hotkey. Ready for multi-monitor-environments, Windows Vista and Windows 7, both 32 and 64 bit versions.

  • Virtually unlimited number of clocks - digital, analog, or both
  • Fully customizable fonts, colors and background images
  • Many pre-configured time formatters (or create your own, even in foreign languages), including Swatch beat

  • Time slider, to temporarily change the time for all clocks within a +/- 12 hour span
  • Show a shadow on "out-of-office" clocks, so you can see at a glance whether it is office time or not
  • Integrated alarm clock with up to 20 separate alarms (for your local time zone or any other time zone) with optional sound signal - use any wav, mp3, wma or mid file (use your favorite song, if you like)
