About the time in Sarnia
Sarnia sits at latitude 42.97, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 13h 36m is one point on that curve, not a fixed value.
Sunrise today lands at 06:44 and sunset at 08:20 local time, giving 13h 36m of daylight. Those figures come from the city's own coordinates (42.97, -82.33) rather than a country-wide average, so they match what you would actually see from a window in Sarnia.
Sarnia follows the civil time used across its region of Canada; there is no separate local reckoning inside the city.
