About the time in Waltham
If you are coordinating from another country, the shortcut is the working window: a normal Waltham day of 09:00–17:00 falls between 13:00–21:00 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 05:58 and sunset at 07:38 local time, giving 13h 40m of daylight. Those figures come from the city's own coordinates (42.39, -71.24) rather than a country-wide average, so they match what you would actually see from a window in Waltham.
Around 60,632 people live in Waltham, and all of them keep the same civil time, so the reading above applies to the whole urban area — not just the city centre.
