"24 hours 4 minutes" because the period of rotation of the Earth is 24 hours MINUS four minutes.
EST = Eastern Standard Time (USA) or England Standard Time (UK); there's no easy way to disambiguate this since it is a common time zone for English speakers in the USA and UK.
"Run clocks backward" a possible reference to the leap second.
"0.9144" because 1 yard = 0.9144 meters
"triple 4 hours after every full moon" = add on an additional 12 hours every full moon, to make the time between full moons exactly 30 "days" (in real life it's 29.5 days). 184.108.40.206 21:44, 7 December 2012 (UTC)
- Erm, just like to say, as a UK resident for all my life (five decades, adult and child), that I've never heard of "English Standard Time". GMT is Greenwich ('Gren-itch') Mean Time, which is for most purposes the same as UTC (which officially took over in the early 70s, but most lay-people still say 'GMT') and all the various other prime standards in use (give or take leap seconds, planetary rotation/orbitting adjustments, adherence to atomic clocks, etc) and BST (British Summer Time, i.e. GMT+1)has just taken over for this sun-tilted part of the year. A brief check of the usual reference sites reveals no sign of EST existing any time since any form of standardised "Railway Time" was originally instituted in the days of the Industrial Revolution, but I might have missed it.
- Anyway, as such, the two ESTs is surely a constructed part of the joke not (as I read it) some fact from RL that needs explaining. Yes, there's EST (Eastern Standard Time) for the US (and versions for Australia and elsewhere?), as well as main Egyptian time-zone and European Summer Time (actually a over-term for the three varieties: Western, Central and Eastern). (The UK roughly matches up to Western European Time and Western European Summer Time accordingly, but that's by no means official except possibly by convention/shared heritage of definition.) But I think the joke with the two 'EST's is purely to do with something like the whole Yard/Metre(/Meter) thing. Although initially I imagined it might be something to do with UK/US Gallon differences, albeit that we now tend to have to use Litres. Or, if you prefer, 'Liters'. ;) 220.127.116.11 21:49, 1 April 2013 (UTC)
I seem to recall that Narnia time ran usually much faster but sometimes much slower than real-world time. 18.104.22.168 20:51, 10 March 2013 (UTC)
I always thought that Taiwan, Province of China missed a golden opportunity here to establish propaganda that they founded it. Instead they are known as a township in the US. 22.214.171.124 20:01, 13 March 2013 (UTC)
