Very nice. As somebody else mentioned, the length of the day would be nice (it could be a third column of times).

The time zone borders map is a bit low resolution so in some places it gets it wrong (for example the northern sides of Roche Harbor, WA and Eastport, MA). Also seems to be a few years out of date (doesn't show America/Santa Isabel). But I expect these are outside your control.

Sometimes it's nice to know the expected daylight in a place that you might visit later in the year, so a way to choose the day of the year would be useful. Perhaps a year-long slider across the bottom of the page that points to a date (defaulting to today)?
