The utility model can use by following method:

One, meridian rotating disk 3 is represented hour hands, and minute hand 4, second hand 5 whole world are public.Rotating disk 3 is distinguished Internal and external cycle during by 24 and is formed 12 fan-shaped equal portions and represent 12 time zones, and 12 hour hands are represented in these 12 time zones, and certain hour is pointed in certain time zone, and this time zone is exactly an individual hour.

Two, the rotating disk name of enclosing the land at home and abroad is identical with the pairing inner ring place name hour, but time morning and afternoon is opposite.As shown in Figure 1 Washington be the morning 9 pairing inner rings Jakarta be points in evenings 9, the rest may be inferred by analogy for it.

Three, the tubbiness line in the chelsea, the expression first meridian, the tubbiness line in the Wellington place name is represented day line (international date line).London is opposite with morning and afternoon at Apia hour, and Wellington is opposite with morning and afternoon at Paris hour, and London is 2:00 AM as shown in Figure 1, and then the Apia is points in afternoons 3.Wellington is 2 pm, and then Paris is a 3:00 AM, otherwise opposite.

Four, distinguish today yesterday: the hour of mainly seeing thing No.12 District (day line) Wellington according to the time zone correspondence, if thing No.12 District day line is the time in the morning, explanatorily the revolutions longitude is less than 180 degree, and promptly time zone, inner ring east does not all enter next day, and date line is in eastern time zone.If thing No.12 District day line is the time in the afternoon, explanatorily the revolutions longitude is greater than 180 degree, and promptly time zone, inner ring east all enters next day, and the date change is in time zone, west, outer ring.As shown in Figure 1, first meridian London is 2 pm, according to the time zone correspondence, just the Wellington of knowing day line is a 2:00 AM, as can be known, existing two time zones, the whole world enter next day, i.e. the Wellington of eastern No.12 District, the Noumea in Shi Yi district, east, earth rotation longitude 30 degree this moment (2 * 15 degree) time zone, date line inner ring east, eastern time zone all do not enter next day.
