The OnTime Ethernet powered digital clock. Not just network powered, but network updated too, for that extra special bit of real geek cred. From $195.00 with pen protectors.
The OnTime clock plugs into an Ethernet jack on your local area network. No AC plug is required, so installation is inexpensive and it’s easy to move clocks around. Power is supplied over the data wiring using the IEEE 802.3af Power over Ethernet standard, the same power source as Voice-over-IP telephones. The OnTime clock is highly accurate, and gets its time updates automatically over the network. It requires no specialized software – control one or hundreds of clocks from any PC on the network with a simple telnet session.
