Mars clock
Ack Ack Ack Ack Ack!It was my friend Peter who got me into timekeeping "nerding". He is a devoted fan of Mars colonization and author of few articles about timekeeping on other celestial bodies. He inspired me to make a simple app to help me (and you!) to see what time it is on other places in our Solar system.

Prime Meridian | 19:24 | 11-05(Aqu)-222 | ------------------------------------------------------ * 0 offset time zone
The idea was to create the most humanly readable modification of the Darian calendar On contrary to the original, the epoch starts on UTC 00:00 11th April, 1609 (invention / first use of telescope) with year 1, not year 0. Aditionaly, the time zone with zero offset was chosen not conventionally (the first landing spot / prime meridian) but rather by matching the converted time with actual daylight on the Red Planet.
Note, that original Darian calendar designates the first day of each month as the start of a new week, which results in a one-day weekend occurring three or four times a year. I am uncertain how this would be received by future Martian colonists, so I didn't implemented this feature as well as winter/summer time shifts or any holidays whatsoever.
Also, the clocks are not updating automatically like clocks usually do, because I didn't want to DDOS myself nor invade your client with any scripting. It is also not very useful extraterrestrially, so I made a portable version which you can fit on your Raspberry Pi or any device running Java. It runs in GUI mode and terminal as well.
