There seems to be a bug in the Android app with regards to the timezone in some screens.
I am in Central European Time (GMT+0100).
Android is configured to get time and timezone information from the celluar network (no special manual setting or anything)
If I open the Ring app and press the global history button above the list of devices, times displayed are correct for my local time.
If I select my Ring Pro doorbell first, and then access its history, it indicates GMT+0000 and the wrong time.
