About the time in Rochester
Rochester sits at latitude 41.06, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 13h 30m is one point on that curve, not a fixed value.
Rochester runs on America/Indiana/Indianapolis, which puts the city UTC −4 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.
The zone identifier America/Indiana/Indianapolis is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/Indiana/Indianapolis keeps pointing at Indianapolis time whatever the date, which is why every timestamp on this page is built from it.
