It could also be a picture map of the world with inbedded analog or digital time-displays.
A moving circular map of the world, rotating inside a stationary 24 hour dial ring
Alternatively, the disc can be stationary and the ring moving.
Light projection onto a map representing daytime, used in the Geochron, a brand of a particular form or world clock.
There are also worldtime watches, both wrist watches and pocket watches
Sometime manufacturers of timekeepers erroneously apply the worldtime label to instruments that merely indicate time for two or a few time zones, but the term should be used only for timepieces that indicate time for all major time zones of the globe.
A time zone is a region on Earth, for example Europe, more or less bounded by lines of longitude, that has a uniform, legally mandated standard time, usually referred to as the local time.
By convention, the 24 main time zones on Earth compute their local time as an offset from UTC (see also Greenwich Mean Time).
Local time in each time zone is UTC plus the current time zone offset for the location in question.
In theory, the increase proceeds eastward from the eastern boundary of the UTC time zone centered on 0°, increasing by one hour for each 15°, up to the International Date Line (longitude 180°).
A corresponding one hour decrease relative to UTC occurs every 15° heading westward from the western boundary of the UTC time zone, up to the International Date Line.
Time zones are adjusted seasonally into standard and daylight saving (or summer) variants.
Daylight saving time zones (or summer time zones) include an offset (typically +1 hour) for daylight saving time.
Standard time zones can be defined by geometrically subdividing the Earth's spheroid into 24 lunes (wedge-shaped sections), bordered by meridians each 15° of longitude apart.
The local time in neighboring zones of Vilnius would differ by one hour.
However, political boundaries, geographical practicalities, and convenience of inhabitants can result in irregularly shaped zones.
Moreover, in a few regions, half-hour or quarter-hour differences are in effect.
Before the adoption of time zones, people used local solar time.
