thank you p.s. i hope i have this under right thread

The obvious method is to actively watch the kids when they're online. Most software out there like NetNanny, etc, monitor content, not activity time AFAIK. Some isp's with software, like AoHell, offer 'parental control' timers which automatically disconnect the isp when their time is ended.

A bit of googling revealed the following links for you:

http://www.akrontech.com/
which takes you to a site selling ENUFF software - a timer which is exactly what you're looking for. It offers a free trial time on the software, but wants $34.95 after the 30 day free period is up.

I also found a good review site on various parental control softwares here:

As for filtering content, I suggest checking out NetNanny and Cyberpatrol. Here's the links:
http://www.netnanny.com/
http://www.cyberpatrol.com/

Once again, these are pay softwares, but both appear to have free trial periods.

Hope that helped!
