advise: need timed web application

[notuo]

Hi. I hope you can help me on this.

I am developing a series of tests in a web page,that par is the easy one. My issu (and I am lost) is every test has to be timed, ie. after certain period of time, the test must end at that point.

This should not represent a great problem but here in Mexico we suffer for power loss, so if the person is answering the test and the power goes off, I am not able to know the remaining time for the test.

I am completely ni blank with this. Any advise is really appreciated.

Thanks for any help and have a great weekend.

Nice idea thanks.

I'll figure the ajax thing (never used really).
