What is picture of time zones?

A picture of time zones shows the different regions of the world that have chosen to adopt a specific standard time to coordinate activities and schedules. The picture typically illustrates the longitudinal divisions of the earth into 24 time zones, extending from the Greenwich Meridian line at 0° longitude, which is used as the reference point for all time zones. Each time zone is usually depicted in a different color, corresponding to its geographical area, and is labeled with its standard time, such as Eastern Standard Time (EST) or Central European Time (CET). The picture helps people to visualize the world's time zones and to understand the time differences between different regions, which can be useful for global travel or communication.
