Air Clock by Alison Pitt (2009)
This clock is designed to look like KDE 4.3's "Air" clock, but from inside Conky.
You can adjust the clock's radius and placement, as well as the size and offset of the drop shadow. You can also choose whether to display the seconds hand. This clock updates every time Conky does, so if you want to show seconds, it is recommended that you set update_interval to no more than 0.5s. If you turn off seconds, you can set the update_interval to as long as 30s. The settings are in the "Settings" section, starting at Line 21.
Call this script in Conky using the following before TEXT (assuming you save this script to ~/scripts/clock.lua):
lua_load ~/scripts/clock.lua
