When we see maintenance notifications or otherwise and they have DateTime’s attached to them they should be converted to system local time.
For example I am in CST and all notifications are in PDT:
“We will be performing scheduled maintenance beginning on Tuesday, April 23rd, 7am (PDT)…”
My suggestion would be to just store and return the DateTimes as UTC values from the API and convert in the app. It’s just a small detail but it’s really a nice thing to have in any app.
