About the time in Río Sur
If you are coordinating from another country, the shortcut is the working window: a normal Río Sur day of 09:00–17:00 falls between 16:00–00:00 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 06:08 and sunset at 07:16 local time, giving 13h 08m of daylight. Those figures come from the city's own coordinates (32.24, -114.94) rather than a country-wide average, so they match what you would actually see from a window in Río Sur.
Clocks in Río Sur stay put all year. There is no summer-time switch to remember, so UTC −7 is what you will get in January and in July alike — useful if you book recurring calls with people in Mexico.
