Wrong date

The wedge of the app doesn’t show the correct date until you go into the app, and coming back out it still show wrong in the wedge.

Wrong date in widget.

When checking the zulu and local time in the app the zulu date will be correct, but when you have a widget set up, the Zulu time might show the wrong date. In the widget, the Zulu time will always have the same date as the local time even if the zulu time is a day ahead.

very useful

i can’t give it 5 stars because of a glitch- mountain time is displayed as the same as pacific time. this would only be accurate in arizona which doesn’t keep dst. otherwise a great app.

update: glitch corrected.
can't imagine a better app!!
