Hello,
I'm having a similar issue with the time settings.
I have a hosted feature service that is shared with members of my professional community all around the globe.
When analysts are putting the data into the layer, they are referencing information reports that give the time of the event in UTC+0, or what we call "Zulu" time. We do this because the community has agreed to use a standard time zone for all reporting to avoid confusion. No matter what time zone you are in locally, the event will be reported uniformly as "0700Z(ulu)."
When the analysts copies the time from the report, he unwittingly is putting the wrong time, as the system is assuming he means local time.
My need is two fold:
A) I need to be able to run the layer on a uniform time zone of UTC+0
B I need the time to display for all analysts around the world in UTC+0 and not in their respective local time zones.
