This is my hands-down favorite clock for the iPad, and could well be the coolest astronomic/civil clock I’ve ever seen: http://emeraldsequoia.com/eo/
Emerald Observatory has everything a time geek could ever want, plus everything an astro geek would want, all in a stunningly elegant interface.
[decription below from Emerald]
Emerald Observatory displays a wealth of astronomical information all on one screen, in a unique but understandable format.
- Times of rise and set for the Sun, the Moon, and the 5 classical planets
- Times of the beginning and ending of twilight
- Heliocentric orrery (display of the planets in orbit around the Sun)
- Altitude and azimuth for the same bodies (one body at a time)
- Current phase and apparent orientation and relative size of the moon
- Current regions of day and night on a world map
- The Equation of Time, solar time, UTC time, and sidereal time
- Month, day, year, and leap-year indicator
- Daily alarm
- Displayed times are synchronized via NTP to “atomic clock” standard
- Uses iPad location, or the latitude and longitude may be set manually
A setting is available to allow the display to stay on continuously.
Tap on the display to move forward by a month, day, year, or minute.
