Game Update exact time for world around time zones please

I don’t know Nelson’s exact time zone nor the hour when Game Updates go live. I know they happen in GMT+9 overnight for every time, it was after waking up from bed that I would find out Unturned got an update. This wasn’t really much of an issue, but now as a server owner, I would like to automatize a server restart so my players are not left waiting for me to wake up and update server version. Can I know the hour in which it happens?

I believe Nelson’s time zone is UTC-6

You can do that. That way you don’t need to know eh updates drop. Nelson also announces them via Spidey, a bot over on UO.
