Spend a lot of time on the Internet via a modem and you lose track of how long you've been connected. Double-click on the icon that looks like little monitors located on the taskbar. The message box will tell you the Duration time, that is, the amount of time the current connection has been active. Note: If you're connected via LAN, this icon won't appear on your taskbar because it's a modem-only icon.
