13:53
MAYBE
Checking your clock…
Yes, San Francisco is awake at 20:00 — so are bakeries and security guards. That does not make your product question a gift. Async is a religion until someone in London needs a decision; then the 08:00 Pacific standup appears. The polite window around SoMa is 09:00–18:00 local. San Francisco still shifts with daylight saving (UTC−8 in January, UTC−7 in July). On an ordinary weekday in San Francisco, treat the desk as reachable only in local business hours.
