About the time in Groton
Groton sits at latitude 45.45, in the temperate-north band, so day length here swings sharply between midwinter and midsummer — today's 13h 50m is one point on that curve, not a fixed value.
Sunrise today lands at 06:40 and sunset at 08:30 local time, giving 13h 50m of daylight. Those figures come from the city's own coordinates (45.45, -98.10) rather than a country-wide average, so they match what you would actually see from a window in Groton.
If you are coordinating from another country, the shortcut is the working window: a normal Groton 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.
