13:52
MAYBE
Checking your clock…
In Tucson the local lexicon for a late ping is not 'async' — it is a flare. No DST, university rhythms, and summer hours that start earlier to beat the heat. The polite window around Downtown Tucson is 08:00–17:00 local. Daylight is honest here; if it looks like evening, it probably is. Ping their late morning unless you already share an on-call rota. Tucson does not shift for daylight saving; the clock stays UTC−7 all year.
