Is there any emergent rule for verb tenses for dealing with action across time zones?
Today is 26 Jan in the US, but right now it is already 27 Jan in Australia. Do I, in the US, say "Today is Australia Day" or "Today was Australia Day"?
(Edited from comment, thanks Hank!) The context was a casual conversation, brought up as (no offense to Australians) trivia or "Did you know?" facts. My location was in the US, where the day is not recognized, and at the time it was 27 Jan in Australia.
A 10th grade grammar textbook near at hand shed no light on the subject, neither was the topic mentioned by Miss Manners (on the chance it was solved by custom.)
