I propose a new timezone, ESOtime. It would be standardised across all servers so that the time given is the ESOtime which would make it easier to coordinate events. There could even be an ESOtime clock optionally in game and a phone app.
Maybe as long as it matches ESOtime. I see allsorts of timezones listed in guilds. Including on the EU server guilds listing things in American timezones. I find it annoying.
This, military uses it as they might have to operate air strikes from other time zones and coordinate this with infantry at location.
One of my guild uses UTC another used central european time.
Guilds tend to specify their time
