Some colleagues of mine recently got new computers and wanted to install the little desktop clock/sticky note application I wrote several years ago. I call it Clocker and have created a new installer to make it easier to deploy. It has the ability to sync your clock to an SNTP time server on the Internet.
The download is a fully functioning, no cripple-ware, application. It requires Windows 2000/XP/Vista with the latest updates. It also requires the MS XML Parser (installed by XP sp 2 or Vista automatically.) It will also update with the latest temperature and conditions based on the zip code you provide.
You can get the installer here.
