About the time in Mountain Brook
Mountain Brook runs on America/Chicago, which puts the city UTC −5 from Coordinated Universal Time right now. The clock at the top of this page is not copied from your device: it is anchored to our reference timestamp and re-rendered every second against the IANA time zone database, so it stays right even when a laptop or phone has quietly drifted.
If you are coordinating from another country, the shortcut is the working window: a normal Mountain Brook day of 09:00–17:00 falls between 14:00–22:00 UTC. Convert your own hours into UTC once and you can tell at a glance whether someone there is likely to be at their desk.
Sunrise today lands at 06:13 and sunset at 07:27 local time, giving 13h 13m of daylight. Those figures come from the city's own coordinates (33.50, -86.75) rather than a country-wide average, so they match what you would actually see from a window in Mountain Brook.
