Hello,

I have a webcam and was able to send images to my webpage that is
refreshed every 30s. My webcam is not always plugged in. My question
is,if someone visits my webpage, how will they know if the images are
really live or from a few days ago when my webcam was last plugged in?
Let's assume the date doesn't not appear on the images. Would I need
to insert some html or javascript code in my webpage to check if my
webcam is plugged in and then diplay the result on my web page to let
someone know that the images really are live?

Why don't you just create a simple JavaScript, or simply plain HTML, that
displays the date of creation of the page (image)?

My windows' clock is very slow. If my computer is left on for a few
days, my clock looses 10 minutes every hour. Only after I reset my
computer does my clock show the correct time. So how does a web page
know if a web cam image is live or not? Is there a command to query
the usb port to check if a web cam is plugged in?

I don't know of an intrinsic command to check for that, you could probably
accomplish it with some very complex java code, but that would require high
security settings, and MS probably disabled querying for things like that.

As for your clock, you could get one of those tiny freeware apps that
updates your clock from the Internet, that would solve a few of your
problems.

Go to http://www.rocketsoftware.com/rockettime/ and download Rocket Time.
It adjusts your computer's clock against the atomic time servers.

Or, if you have windows 2000 or XP, there's a built-in NTP client. Check
the documentation for the 'Windows Time' service.

Of course, your other option is to replace the cmos battery and not have to
worry about the clock losing time that quickly.

You're not going to solve this with HTML, are you? It can't be done.
You have a number of options:
- get your web cam software to add a time-stamp to the image file

- get your web cam software to craete the page for you and include the
timestamp

- use some server-side scripting to stat the file and get its time
stamp and output that to the HTML document

- don't worry about it. Does anyone (apart from you) really care when
it was last updated?

But I thought my clock is running slow because of the windows98
(software) clock. Isn't the cmos battery for the hardware clock? My
computer always shows the correct time when I first boot up. I though
this means the hardware clock is ok, so I wouldn't need to change the
battery.
