   I have very fond memorys of this train, often travelling from London Victoria to Margate when going on holiday. I used to love the real springy seats and that classic sounding horn. I used to travel on these as a child in the late 80s and early 90s. I used to enjoy traveling on the north kent line then. Now i dont bother. The 375s are boring and without character. Theres just no sense of excitement anymore. Bembom Brothers cheap day return (Dreamland fun park Margate) on hot summer days.

   Dogs, cats and apes are more moral than most human Christian brainwashed zombies. The animal kingdom proves that morality does not derive from a fringe Bronze Age cult — morality is a product of natural selection: those predisposed to cooperation and empathy have a better chance of their genes surviving. Christians are the least moral people I know, especially Christian preachers, hucksters in it only for the money.

   Ok, this is a source of some confusion, but basically here's the scoop:

   There are two systems of time, "Universal Time" (UT1), and "Universal Time Coordinated" (UTC). One day in UT1 is measured by one rotation of the Earth as seen from the average position of the Sun. One day in UTC is measured by 24 hours passing on an atomic clock.

   Now, when it started on January 1st, 1972, UTC was perfectly in line with UT1, and that is actually what defines an hour in UTC time – 1/24th of an Earth rotation in 1972. However, the Earth is very slightly slowing down its rotation due to the moon's tidal force. Specifically, it slows at a rate of .002 seconds a day per century.

   So, in 2072, the UT1 day will be longer by .002 seconds than the 1972 day (and by transitivity, .002 seconds longer than the UTC day, too). In 2172, a UT1 day will be .004 seconds longer than the UTC day…in 2272, the UT1 day will be .006 seconds longer, and so on.

   Now, here's where the confusion comes in: Even though the *rate* of change of the UT1 day is miniscule, it adds up to a large *total difference* in time between UT1 and UTC over the long haul. Note the important distinction in those two: rate vs. total difference.

   In other words, say that right now in 2008, the UT1 day is now .001 seconds longer than the UTC day (it's not quite that much yet, but it'll make the math easier). Let's say that the "time folks" just inserted a leap second so that right now the UT1 and UTC times are perfectly synchronized. Tomorrow, they'll be .001 seconds different. The day after tomorrow they'll be .002 seconds different, the next day they'll be .003 seconds different, and so on. It won't take very long (about 1.5 years) until they're more than half a second off, and they'll have to insert another second to synchronize the two times again.

   The point that I believe both Phil and the USNO is trying to make is that even though the rate of Earth's slowing is relatively small, that can add up to a big difference in a relatively short amount of time.

   Edited for clarity: The confusion that some people have is that they get these two concepts confused…they assume that if we have to insert 1 second every 1.5 years, then the *rate* of slowing must be 1 second/1.5 years.

   This is not true, but to produce a mathematical result that the Earth will come to a dead halt in just a few thousand years (rather than just exponentially longer days), think of this in terms of frequency rather period: When UTC and UT1 are in sync, the Earth makes 1 rotation in 86,400 sec (one UTC day). In 1.5 years, it will only make 0.999988 rotations in 86,400 sec. In 3 years, it will only make .999976 rotations in 86,400 sec. At this rate, it will take 129,601.5 years before it makes zero rotations in that time period. At least, I *think* that's how they come to that conclusion. I'm sure you could greatly shorten that time with the added fact that leap seconds will have to be added more and more frequently as UT1 runs even slower compared to UTC.

   A quick side note: this has absolutely nothing to do with the extra day inserted on leap years – that's simply due to the fact that one year is closer to 365.25 days than just 365 days. Since it's not an integer number, we need an extra day every 4 years to account for that extra 0.25.

   It's working. The sad thing is that immigrants won't stop trying and having to go through those dangerous areas will cause many deaths.
