Sharp World Clock 8.6.0 | 12.3 Mb
Sharp World Clock is a desktop clock program for Windows. It can display the local time for multiple cities and time zones with correct daylight savings. You can decide how many clocks you would like to see at any time. The clocks are resizable without any loss of visual quality (due to the use of hardware accelerated WPF technology). The main window and undocked clocks are resizable and can be dragged anywhere on the desktop.
