    ...which has an extra pip added to it from time to time (ouch) in order to bring it into line with Atomic Time.

    The MSF time signal has extra bits in the first few seconds coded to describe the current offset between it and Atomic Time, just to round this off.

    Au contraire it is UTC or Atomic Time that periodically in theory has to be brought in to line with GMT as it does not allow for the vagaries in the rotation of the earth whereas GMT in theory (bot not in actual day to day practice) does.

    There is only ever a tiny fraction of a second when they are the same. From that moment on, GMT and UTC are different. In common parlance they may be interchangeable, but it doesn't alter the fact that they are different things calculated in different ways, and are not the same thing. Just being common doesn't make it right. In common parlance a metric byte and a computer byte are the same thing, but in actual usage are quite different.

    And it still does. That's why GMT is defined from observation at Greenwich... Which I believe I've already said...

    Its good to hear that Microsoft are directly hooked in to a sundial in Greenwich for their internet time keeping then rather than using any new fangled sort of digital or atomic time keeping device.:p

    I wonder what they do at Greenwich when its raining and cloudy for a week or so in a row.:rolleyes:

    GMT is only used in the zero longitude timezones, and the UK only in the winter. Everyone else uses UTC offsets. The fact that Microsoft et al mislabel things doesn't make it right.

    You seem to be favouring a pedantic and fairly pointless form of differentiation when to most people they are two different terms for the same concept:-

    No, I'm not being pedantic. I'm being accurate. There was a very definite need for a specific definition and a new method of calculating time - that was UTC. It is inherently different to GMT, and you deciding I'm being pedantic doesn't alter the fact that I am correct you are most definitely wrong. But as we know, you never let the facts get in the way.

    There is usually a rather thin dividing line between those two things and it often has to do with whether you are a New Scientist reader or a reader of The Times.

    Regardless of which UTC and GMT are generally the same to all intents and purposes most of the time because UTC is adjusted periodically for deviations from GMT.

    Seems most people agree with me.

    All you are proving here is that kitschcamp is right - they are different! :p

    Always different, but never by more than a fraction of a second. As TiVo operates to the minute level, any differenced between UTV and GMT are therefore not relevant in that context. Everyone knows what GMT is, only geeks know UTC (or UT1 or UT2 or..) are, so it's a reasonable everyday approximation.

    In the same way as we now know Newton's gravity theory is wrong, but it's close enough for everyday use.

    It seems that for once we are near to being in agreement on an issue.:eek::p

    No, I don't think you do. You said:

    whereas TCM2007 says

    You said they were the same, TCM acknowledges they are different.

    It all depends on whether you are a time pedant or not as to whether you think they are different.;):p

    Perhaps we can now have a discussion about UK vs US gallons of petrol which really are different in quantity.

    No, they are different, that's why they have different names and definitions, as you yourself have proven many times in this thread.
    I'll give you a clue, they are called Imperial and US gallons for a reason. They are different. You accept they are different, though. Curious.

    I challenge you to provide an explanation of any significant practical differences for a reader of The Sun newspaper.

    Because they are also actually different for people other than Time Pedants.:p

    That was never the point. YOU claimed they were the same, and that one was "the new name" for the other. That's wrong, as well you know. There is little point continuing this, as you can never be wrong, even when you provide your evidence that you are.

    Stephen - Pete I suspect knows he's wrong, he's just enjoying yanking your 'chain'. Or should that be 'cable' outside Greenwich... :)

    Remember when this thread was about soft padding?
