The clock shows two different times in several different ways. Civil time is the current time in your time zone, taking daylight saving rules into account. Solar time depends on the position of the sun in the sky. Solar noon is when the sun is at its highest point. That moment depends on where you are, and on where the Earth is in its annual orbit around the sun. The time display shows hours and minutes in the way you're used to. It also shows a metric time. It breaks the day into 10,000 equal-sized pieces and keeps count of them over the course of the day. Midnight is 0000, and 9999 is the instant just before the next midnight. It also shows a progress bar for the percent of day elapsed. The clock shows sunrise and sunset times for both civil and solar days, in the hour and minute display and in metric. There's a "classic" display page that shows just solar metric, civil metric and civil hh:mm time. There's a converter page that allows you to type in a time, civil or solar, hours:minutes or metric, and convert to all the other available time types.
