TSD Rally Clock
The TSD Rally Clock allows you to synchronize to the Official Rally Time by making adjustments in increments of +/– 0.1 seconds to account for total errors of as much as + or – 10 seconds.
Touch the Lock icon 🔒 to make clock adjustments. Adjust time ahead or behind as needed and, when finished, touch the Unlock icon 🔓 to prevent unintended adjustments. Touch the double Arrows ⏫ ⏬ singly or continuously to make adjustments in +/– 0.1 second increments.
When unlocked a chime will sound at 0 seconds and at 30 seconds. This audible cue is helpful when synching with the Official Rally Clock.
To clear the list of split times, touch the "Clear Log" button and answer the question "Yes, Touch to Start" or "Yes, Start Next Minute" as desired. Start the rally by touching the clock face or wait until the next whole minute has been reached when the start will occur automatically.
Recording split times can be helpful for comparing your time at a checkpoint to the time recorded by the checkpoint staff. Or, the checkpoint staff could use this feature to record times as cars cross a checkpoint.
Also, split times can be used to track time in what are called Regularity or Jogularity style rallies. The current split time and the cumulative time will be logged in a table and compare these times with those indicated on the route instructions to see how well you are maintaining the ideal pace.
On the clockface displays, time can be measured in either seconds or decimal minutes. Additionally, there are two levels of time precision. One displays two digits for seconds or two digits for hundredths of a minute. For more precision, the other measures and displays seconds as two digits plus tenths of a second or three digits for thousandths of a minute.
There are three replica watches face styles: black, yellow, and white. This improves readability under different light conditions.
