What does UTC time mean?
UTC or Coordinated Universal Time (Temps Universel Coordonn) is the international time standard (formerly Greenwich Mean Time, or GMT). Zero hours UTC is midnight in Greenwich, England, which is located at 0 degrees longitude. Everything east of Greenwich (up to 180 degrees) is later in time, everything west is earlier. The current UTC time is displayed in the upper right corner of the PassageWeather website. If using the PassageWeather forecast images when offline, the easiest way to find the UTC time is to check your GPS, which displays UTC time very accurately.
