FinishTime is a clock for use by marshals working flying finish at a stop control in a stage/performance rally. At the press of a button, it records the time of day in seconds or tenths of a second. These times are saved for later reference. The time of day can be synced with rally time.
The running time of day (in seconds) is also displayed so that it may be used at an Arrival Time Control or Stage Start.
In order to facilitate viewing of the display under a variety of lighting conditions, the brightness can be adjusted and the information switched between being displayed in black or white.
Note: FinishTime will consume a lot of battery power while being used as a flying finish clock on an active stage or displaying the start time to competitors. In either activity, the iPhones screen needs to be illuminated so that the current or recorded time may be seen and acted up/logged/reported to the finish control and the screen can uses a lot of power. Starting with version 1.3, covering the proximity sensor will turn off the screen and save power. Shutting off other parts of the iPhone (like Bluetooth or WiFi) may help extend battery life as well. Of course, this can be avoided by running the iPhone on external power.
