The picture is divided in 24 segments representing the 24 hours of the day. The break between segments is not visible at noon or midnight because of the words, but presumably exists.
The picture rotates by 3.75 degrees every 15 minutes, as does the Earth, so that it is constantly up to date in showing which regions are currently at which times of day. The picture change seems to happen half-way through a 15-minute time increment (that is, at 7½, 22½, 37½, and 52½ minutes after each hour), so that the picture is always correct for the nearest multiple of 15 minutes.
The map projection of the earth in the middle of the picture shows an azimuthal equidistant projection with the South Pole in the center which is uncommon because most times this projection has the North Pole at its center. Randall was playing on projections before here: 977: Map Projections .
The list of cities and countries doesn't always match the map, because the list takes into account local variations in time zones. The map shows the current (February 2014) configuration of time zones with respect to daylight saving time (also known as summer time), which is being observed at the time of the comic's initial release in parts of Australia, New Zealand, Brazil, and other countries not named in this comic. If the map is to stay accurate through the year, the location of place names will have to move over the next few months as parts of the southern hemisphere go off DST and parts of the northern hemisphere go onto it, but we don't yet know whether this will happen.
In many countries, business hours are considered to be from 9 am to 5 pm. With some exceptions, including emergencies, it is generally considered rude to place a telephone call to someone's residence during the hours when most people are asleep (Randall portrays this time period as extending from 10 pm to 8 am). This may be a reference to the 10 pm "cutoff" time discussed in an episode of "Curb Your Enthusiasm."

When first posted, the picture was exactly 12 hours off. Somewhere around 5:10 UTC, this was fixed. The original version also included a listing for Inland Brazil; this could have created a conflict with US East Coast when Daylight-Saving Time begins in the US, and it has been removed.
The names used for the image files refer not to UTC (Universal Time) as one might expect but rather to the time exactly 12 hours off of that. The name of the image file linked from the page matched Universal Time during the first few hours, but the file-naming scheme did not change when the comic was corrected.
