DXN datetime (@datetime "...") — a fixed-offset, non-UTC instant.
Stored as { epochMicroseconds, offsetMinutes }, mirroring
.dxnb's own wire shape (DXN.md §2.2) directly. offsetMinutes
is informational only for toDate(): native JS Date has no offset
concept of its own (it always normalizes to the same UTC instant
either way), so the conversion is lossless for the instant itself
but drops which offset it was originally expressed in.
