t timer

It is a timer application useful for itinerary time management in car rally competitions.
When you set the start time and target time, the arrival time is calculated and the countdown is performed.
5 minutes before, 3 minutes before, 2 minutes before, 1 minute before arrival time will be notified by vibration.
The count continues until one minute after the arrival time. After the arrival time has passed, the number will be minus. The count stops 1 minute after the arrival time.
The start time can be set before or after the current time. If you set the start time to a future time, the countdown to the start time will begin, and then switch to the countdown to the arrival time.
