Russian names a half hour by the hour it is entering, in the genitive, so
"половина восьмого" is 07:30 and never 08:30. Neither date parser read that
shape, so the reminder parsed to nothing.
rewriteHalfPast runs in front of the token pass in SpellOutDigits, so the
python parser and the stub both see "в 7:30". It also reads the contracted
"полвосьмого" and the quarter-to shape "без четверти восемь", which counts
from a cardinal and is 07:45. Minus one is in one place, clockHourBefore, with
twelve rather than zero before one.
Ordinals eleven and twelve added to the lexicon, because a clock reaches them.
Minutes a spoken clock does not use are left alone: a guess here is a missed
dose.
Classifier + onnx over the routing fixture 58/82 to 62/87, three new cases,
none regressed. Python dateparser is not installed on this host, so only the
stub was measured. See docs/evals/2026-08-05-half-past-hours.md.
"напомни мне позвонить маме в семь вечера" answered "не получилось разобрать
время напоминания", while "в 19:00" set the reminder. Reminders arrive through
speech, and speech says the hour in words, so this was the ordinary case
failing and the typed one working.
SpellOutDigits rewrites a spoken number as digits, but only when a time word
stands beside it — "в три часа" becomes "в 3 часа" and "купить три яблока" is
left alone. Both parsers see it: dateparser already rewrites "7 вечера" to
"7 pm" and never saw a digit to rewrite, and the stub floor now reads the
qualifier itself.
