Its habit of getting up late you’ll agree
That it carries too far, when I say
That it frequently breakfasts at five-o’clock tea,
And dines on the following day.
In November 1859, Dodgson gave a lecture at a meeting of the Ashmolean Society on “Where does the Day begin?”. A clock traveling around the earth with the sun always exactly above of it could stand still but always would be correct. (It’s almost like the mad tea-party having always six o’clock while moving around the table.) Only the day date suddenly would change somewhere. (That’s where in Alice’s Adventures in Wonderland the March Hare quickly changes the topic.)
There neither were internationally defined time zones yet, nor an internationally agreed date line when Charles Darwin and the HMS Beagle travelled around the world, but when he (and the Snark) breakfasted in Tahiti, it probably already was around tea time back home in Carroll’s Oxford. From there it carries us far away, when we imagine breakfasting in Tahiti.
On 2020-10-22 I found a twitter thread, where John Pretorius showed, that he interpreted (and applied) Lewis Carroll’s “breakfasts at five-o’clock tea” stanza in the same way as I did.
