About the time in Groton
Around 486 people live in Groton, and all of them keep the same civil time, so the reading above applies to the whole urban area — not just the city centre.
Groton sits at latitude 43.70, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 13h 39m is one point on that curve, not a fixed value.
The zone identifier America/New_York is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/New_York keeps pointing at New York time whatever the date, which is why every timestamp on this page is built from it.
