It’s essential to know the valid time of any weather guidance you may use prior to flight. There are two choices in EZWxBrief for time, namely, device time (local time) and Zulu (GMT or UTC). In EZWxBrief you will find times listed in many locations throughout the progressive web app such as the EZRoute Profile or on the EZMap views. You have the option of displaying local or Zulu time based on your preference. You can make that choice in your EZSettings as shown below. In this case, Local time has been chosen.
When the time preference is set to Local, that will change any times displayed within the app to your local time or the time default on your particular device. The only exception is the Zulu clock (shown above) which always displays the current Zulu time regardless of your settings preference. Often Zulu time may occur on various static weather images, so it is convenient to always have the current Zulu time displayed.
If you set your preference to Zulu as shown below, you will notice a Z located behind each time listed in the application. If there isn’t a Z shown after the time, then you have your preferences set to the device time (local). Keep in mind, on most of the static weather images that Zulu time is rendered. EZWxBrief does not alter any of these images when the time preferences are change. However, the time slider in the EZImagery view will change to satisfy your time preference.
