EDIT: But I went and looked it up and you are correct, you gain 2 minutes of time at sunset but lose 4 minutes in the morning, between now and 12/21.
I'm curious as to the reason.
time zones are an approximation. they don't provide infinite granularity. and as mentioned, celestial mechanics are not as an exact science.
