In most cases, standard time is based upon some meridian of longitude which differs by a multiple of 15° from the Greenwich Meridian i.e. standard time differs from Greenwich Mean time by a multiple of hours. Standard Time for the UK is Greenwich Mean Time and that for France would be Central European Time (CET) being one hour ahead of GMT.
