MAYBE
Checking your clock…
People in Tulsa keep office hours that look familiar on a slide and stranger in practice. The polite window around Downtown Tulsa is 08:00–17:00 local. Energy-town Central Time. Evening Slack is a leftover, not a request. Daylight is honest here; if it looks like evening, it probably is. Ping their late morning unless you already share an on-call rota. Tulsa still shifts with daylight saving (UTC−6 in January, UTC−5 in July).
