Time in TWL 2000

[Marc]

I haven't looked at a "Poor Richard's Almanac" in years, but if I recall they had charts that showed sunrise and sunset times for many locations in the US. For example: If you know that the town you are in is due North or due South of Nashville, you can use the Nashville times for sunrise/sunset and set your clocks accordingly.

This makes me thing in the only reading my father-in-law practices in a normal year. The Almanac del pags, more or less The farmer"s Almanac. Beyond the normal references to de duration of the day, festivities and markets, he follows the calendar of the almanac for his agricultural duties. When to plant this, when to prune that... Hmmm it seems a valuable possession for a Twilight character...

Hmmm I just thought of a great mission for the characters... the seed vaults buried in arctic and manuals like the Farmers Almanac...

I guess my real question is who is going to be the keeper of the official time The worlds atomic clock was probably destroyed in one of the nuclear attacks and after batteries die in watches who is going to be the one to say what Zulu time really is

Just curious.

Well, you have various atomic clocks and other time system countries use. WWV is in Ft. Collins, Colorado and they broadcast their atomic clock signals on shortwave. You have WWVH in Hawaii doing the same thing. In Canada, you have their atomic clock on CHU in Ottawa. I know most European countries have time clocks as Russia and Red China. Australia has one and there are a couple in South America too, Columbia and Venezuela I think. Maybe South Africa too, I'm not sure. I guess the three candidates would be the South American and Australian ones although MilGov might get WWV going again. IIRC, WWVH is on the big island in Hawaii so that could escape damage too. Another problem is maintenance issues too, how easy is it to maintain atomic clocks. I know before atomic clocks were used, they used electronic quartz systems from the 1920's to now. Also you would need the astronomers to check accuracy too.

Time yes, but location will be seriously wrong after 3+ years without updates (of course you tend to need more than one satellite anyway for a fix so it's probably a moot point).

I'm not sure of the details, but the GPS satellites all have to have their clocks updated at least once every 24 hours. Something to do with the way gravity distorts time (yes, you read that right). A clock aboard a GPS satellite tends to run about 7 microseconds slower than an identical clock on earth.

Sounds more like the compensation for Einstein's Theory of Relatively where the faster you go, the clock goes slower, remember those satellites go at 18,000 MPH as they orbit the Earth.
