MAYBE
Checking your clock…
In Regina the local lexicon for a late ping is not 'async' — it is a flare. No DST, prairie hours. Do not copy Winnipeg's clock in November. The polite window around Downtown Regina is 08:00–17:00 local. Winter daylight collapses early, so an afternoon ping can already feel like night. Ping their late morning unless you already share an on-call rota. Regina does not shift for daylight saving; the clock stays UTC−6 all year.
