As a user in another country, I think it would be a good idea to display the US local time for KingIsle somewhere on the homepage or forums.
This is especially true for server downtime. It is difficult for many adults let alone kids to learn how to adjust timezones and knowing which US time zone to use just adds to the complexity.
Re: A clock showing the time in King Isle's timezone.
:( I have to agree; I can't even keep the clocks in my house on the same time, so why expect people half around the world to live on a clock they never actually see? :(
