Time zones are a clumsy social artefact.
GPS provides an acceptably accurate UTC reference, plus latitude and longitude.
Now ... if you know your exact longitude, and UTC, you can quickly calculate your local time. Not just your time zone, which is smeared over 15 degrees, but the precise "time" where you are at that moment.
So, for example, if you travel West from Greenwich until you reach Reading, when it's 1200 in Greenwich, your BorgCo Local Clock would tell you it's 1156.
However, if you travel East from Greenwich to, for example, Lowestoft, when it's breakfast time in London, in Lowestoft it's still only 1951 ...-- 8th of 7, Dec 10 2017 Tom Tower time greenwichmeantime.com/info/oxford/ [pertinax, Dec 10 2017] Yes, I can see this sort of thing being immensely helpful.-- MaxwellBuchanan, Dec 10 2017 This was baked some time ago, in the setting of the clock in Tom Tower, Christ Church college, Oxford. See link.-- pertinax, Dec 10 2017 Yes, and Brunel's railway station in Bristol has a clock with two minute hands.
That's not the point. Those clocks are fixed with respect to the zero datum.
The clock we're describing varies continuously with varying longtitude, so it displays true corrected time at your current location. At 1200 by this clock, the sun will always be due South.-- 8th of 7, Dec 10 2017 UK train clocks could simply to be connected to a device that was linked to the actual arrival time, meaning that the trains will always arrive exactly on time, according to them of course. This would be referred to as Alternative Time.-- xenzag, Dec 10 2017 //Time zones are a clumsy social artefact// And *so* 19th century! - Where is the post-general relativity alternative?-- hippo, Dec 11 2017 //At 1200 by this clock, the sun will always be due South.// Not always, mate.-- AusCan531, Dec 11 2017 If it doesn't, all you have to do is wait for the next pole reversal ... due any time now.-- 8th of 7, Dec 11 2017 Nice, the faster you move the west the faster the minute hand goes backwards. Well, at the equator at any rate.-- wjt, Dec 15 2017 Since if you are actually on the train it does not move relative to the observer, the legal position is unclear.
In fact, the problem is that the planet has failed to move fast enough relative to the train, and thus the observer. This is called "slow planet syndrome" and is a well-known phenomenon. We suggest that the obvious redress is to issue proceedings for damages against the Astronomer Royal and the Royal Observatory, Greenwich.
We suggest that a further action against the executors of the estate of Werner Heisenberg would be advisable, although it's likely that finding their current address to send documents to will be impossible.-- 8th of 7, Dec 15 2017 Would that be "Late, as in the late Dentarthurdent ?"-- 8th of 7, Dec 15 2017 Only if you evolve into something with far longer arms (but which is probably quite incapable of drinking the coffee).-- 8th of 7, Dec 15 2017 Well, don't stand here waiting for your coffee - you need to be in that line over there. Far queue, [Ian], far queue.-- MaxwellBuchanan, Dec 15 2017 No, don't send him over there, get him to stay here and demonstrate his amazing ventritussive skills ... please, [IT], just Far Cough. Please?-- 8th of 7, Dec 15 2017 Was that the one that you use to play sheet music ? We're sure that someone mentioned that when you play music, it's always sheet ...-- 8th of 7, Dec 15 2017 On that note ....-- normzone, Dec 15 2017 ... the case of the People vs. [normzone] was proven.-- 8th of 7, Dec 15 2017 All this goodwill warms my heart. I can see daisies springing up wherever [8th] treads, and little birds start to trill (if only because they know they're safe from cats). Then off he trips to peace on Earth from orbit.-- pertinax, Dec 15 2017 At this festive season, we hope that the spirit of goodwill lights up the lives of not only other halfbakers, but up yours.-- 8th of 7, Dec 16 2017 I hope other bakers have some festive snow this Christmas. So far it's only reindeer.-- MaxwellBuchanan, Dec 16 2017 That will undoubtedly depend on the type of connection that they have - you'd better look into that. Socket and see ...-- 8th of 7, Dec 16 2017 I hear they also pay good prices for used iMacs. I might try to find some - an iMac hunt.-- MaxwellBuchanan, Jan 03 2018 random, halfbakery
