RasTimer is a tiny program for Windows that allows you to keep an eye on your Internet connection time. As soon as you establish a Dial-Up Networking connection, the program starts counting the time.
RasTimer appears as an icon next to the system clock in the system tray. With that icon, you can find out the length of your current connection as well as the connection's history.
With the current version, you can export or print a report of the connections. It's also possible to delete connections, and records of days or months that you no longer need.
