    I had an idea when I was walking to school. Because the time difference is 1 hour from London to paris there would be like seconds and minutes time difference in between right? So i thought i could work out the time difference between london and were i live! To work this out I would reaserch how many Km or so it was from london to paris and then divide that by the time difference to get the difference in time per km. You would then times that by how any km your are away from London to get your time difference. I realise this would only work for the half of the uk inbetween paris and london and it's not much use but I thought it would be funny! Would my idea actually work?

    Two remarks:

    First, the official time zone is one and the same for all of the UK, and another one zone for most of continental Europe (including Paris and all of continental France). You do not have an intermediate official time for your place. The UK official time is probably close to local solar time for London because it's centered on the Greenwhich meridian. The Central European zone is not centered on Paris. The distance between Paris and London is not as closely related to the time zone difference as you imagine.

    Second, what matters for time zones is not distance but difference in longitude. Angola has the same time zone as France (except when France has daylight saving time), although it is much further from it than the UK.

    I suggest you determine your local solar time by using a compass and some vertical pole that casts a shadow (such as a lamp post). When the shadow points due north, it is noon according to local solar time.

    Good luck,
    Leszek.

    You are very welcome.

    I beg to disagree. You devised a very logical thought experiment, driven by curiosity. You lacked some information, and you asked for it in the right place. Keep up the good work. Curiosity is the mind's healthy appetite.

    Cheers, Leszek.
