It's still morning in Honolulu

...but it's tomorrow in Tokyo.

I don't think it's yesterday anywhere, although as of 1 AM this morning it was yesterday in Honolulu, if I am not mistaken. Which reminds me of the 'how to prove Santa Claus exists' theory, dramatized by Raymond Smullyan approximately as follows:

Logician 1: Santa Claus exists, if I am not mistaken.
Logician 2: Well of course he exists if you are not mistaken.
Logician 1: So you agree I am correct.
Logician 2: Yes of course, I just said so.
Logician 1: Or in other words, I am not mistaken.
Logician 2: Yes. Um, wait...
Logician 1: And we agreed that if I am not mistaken then Santa exists.
Logician 2: Just a minute...
Logician 1: Therefore, Santa exists!
