The Time Zone layer allows you to improve your time perception. Like all layers, you can combine it with any of the available Map Types or other MarineTraffic features (Fleets, Filters, Layers) to get the information you want directly on the Live Map.
For your information, a Time Zone is a region of the globe that observes a uniform standard time for legal, business and social purposes. Coordinated Universal Time (abbreviated to UTC) is the essential time standard by which the world regulates clocks and time and is displayed in this layer.
To activate it, simply click on the corresponding checkbox in the Layers section of the Live Map Toolbar.
Detect any vessel on the Live Map, hover over the surrounding area and you will be able to tell the Time Zone (GMT-based) there, on the top right corner.
