Chronometer
Short Name:
chrono
Creates a new widget that displays how long it will take your character to perform various actions. Works in Minimalist or Classic UI. Full UI functionality (scale, move, etc). Mouse over an NPC or projectile to see how their speeds compare to yours. Enable verbose mode from "Chronometer" in main menu for even more info about your moused over targets' speeds.
Due to MD5 woes, the earlier Chronometer page has been lost (along with my votes :( )
