It’s essential to know the valid time of any weather guidance you may use. There are two choices in WeatherSpork for time, namely, device time (local time) and Zulu (GMT). In WeatherSpork you will find times listed in many locations. You have the option of displaying local or Zulu time. You can make that choice in your Preferences view as shown below.
If you set your preference to Zulu (as shown above), you will notice a Z located behind each time in the route profile as shown below. If there isn’t a Z, then you have your preferences set to the device time (local).
