Monitoring connection uptime

[Baj]

My adsl connection has started frequently dropping.

Its def the connection, I'm even plugging directly into the BT master socket, and have tried 3 different filters.

 

What I am after is a piece of software (mac, xp or linux) that can monitor the adsl uptime and produce a report like "went down at 12:33 for 6 minutes" or anything similar.

 

Does anyone have a suggestion?
