Is this true on both solstices or just the summer solstice (in northern hemisphere)?
The sun is (surprisingly) further away at the (northern) summer solstice, so I would expect its angular diameter to be less and therefore the change from center to rim would occur more quickly.
If it's for both solstices, then I'm at a loss for an explanation and leave it to the more erudite members of this list (whoops, sorry for using "list," the more erudite members of this GROUP) to explain...

Subject: [NavList] Speed of Sunset
Am I the ONLY person amongst this august group who didn't know that the altitude of the setting Sun is different Solstice to Equinox? (the speed the center of the sun sets- angular size only changes +/-1 min.Somebody could use this with their sweetie- "Honey, you know what day this, don't you? The Sunset is fading fast, so Kiss Me Quick.In Summer/Winter, 2 min 30 sec, in Fall/Spring, 2 min 21 sec. If you are skeptical, ask any Astrologer.
