I need to block access to certain websites during certain time. For example I want to block from 0600 - 2000. The settings should be password protected. If I could redirect them to here during the block hours it would be a bonus.

I do not have access to the router and the OS is Vista.

There are several related questions but I couldn't find a duplicate.

K9 web protection can block certain sites, and it can shut off internet access during specified periods of time, but I don't think it can just shut off certain websites at certain times of day. It does however let you enter a password to temporarily bypass the security blocks. It is also local to the computer it is installed on.
