Grammatical Errors of the Chrono-Cartographer

Warning: The following is a list of egregious grammatical transgressions, committed during a period of intense chrono-cartographical research.

• The chrono-cartographer's notes are full of who's instead of whose. It seems they were under the mistaken impression that the possessive form of the word was whos.
• In an attempt to convey the complexities of time-space, they confused the use of then with than, resulting in several sentences that defy logical interpretation.
• The chrono-cartographer's writing is full of their instead of there, there instead of their, and they're instead of they are. It's a wonder they managed to map the space-time continuum at all.

Or, if you will, Temporal Tangents
