I'm not looking for a history of watches, or time pieces, I have researched that already. I'm looking for the origin of the association of the word "watch" itself with portable time pieces, and how or why it came to be.

Is there any website showing the time in different nations online? It should be just like a wrist watch showing all national times, available online so that we can see it now and then while we are browsing internet. In USA, is there only one national time followed or different states follow different time? If different, is there any source to find a list? Please help, even if a chart showing the difference of time (at least) is available.

The switch I am looking for is special in that it does not allow you to throw any other poles on the switch untill you open the first poll.
It works similar to this:

(press button 1)-(cant press any other button)-(press button 1 again)-(can press anyother button)...

I have a 3 pin Bi-LED, two anodes and one cathode. I am using it with
two transistors, each transistor controls a anode. The only way I can
sucesfully use this Bi-LED is if I attach 2 signal diodes to the
cathode (gnd), thus creating two seperate cathodes, connecting them to
the collector of the transistor.

How will this effect the formula in choosing a resistor on the Bi-LED's anodes? I would assume that a smaller resistance would be chosen.
It should be noted that one of the transistors are also powering a 150mA relay.

This relates to solar panels installed at residential properties (or commercial for that matter...as long as it's NOT large-scale) for electricity generation.

This also does NOT relate to solar thermal installations.

(If you find information about large-scale installations, please answer my other question: http://answers.yahoo.com/question/index;_ylt=AljDBaffejhKbeE9V3okrafsy6IX?qid=20060812044222AARJkwf )
