&lt;hr /&gt;
&lt;div&gt;Think of what Jack Bauer could have done with 4 more minutes!&lt;br /&gt;
&lt;br /&gt;
&amp;quot;24 hours 4 minutes&amp;quot; because the period of rotation of the Earth is 24 hours MINUS four minutes.&lt;br /&gt;
&lt;br /&gt;
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.&lt;br /&gt;
&lt;br /&gt;
&amp;quot;Run clocks backward&amp;quot; a possible reference to the leap second.&lt;br /&gt;
&lt;br /&gt;
&amp;quot;0.9144&amp;quot; because 1 yard = 0.9144 meters&lt;br /&gt;
&lt;br /&gt;
&amp;quot;triple 4 hours after every full moon&amp;quot; = add on an additional 12 hours every full moon, to make the time between full moons exactly 30 &amp;quot;days&amp;quot; (in real life it's 29.5 days).

: Erm, just like to say, as a UK resident for all my life (five decades, adult and child), that I've ''never'' heard of &amp;quot;English Standard Time&amp;quot;.  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 &amp;quot;Railway Time&amp;quot; was originally instituted in the days of the Industrial Revolution, but I might have missed it.&lt;br /&gt;
&lt;br /&gt;
: 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'. ;) [[Special:Contributions/178.99.20.83|178.99.20.83]] 21:49, 1 April 2013 (UTC)&lt;br /&gt;

I seem to recall that Narnia time ran usually much faster but sometimes much slower than real-world time. [[Special:Contributions/130.160.145.224|130.160.145.224]] 20:51, 10 March 2013 (UTC)&lt;br /&gt;

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. [[Special:Contributions/66.88.136.254|66.88.136.254]] 20:01, 13 March 2013 (UTC)&lt;/div&gt;</summary>
