A very simple mod that adds a timer that can be controlled with console commands.
At the start/end of the timer the game speed can be adjusted with a command to speed up testing /slow down testing if desired.
Made this mod for myself to calculate the troughput of trains on a given intersection.
Maybe someone will find use in this aswell.
/timer_start - Starts the timer
/timer_stop - Stops the timer
/timer_set_duration - Sets the duration of the timer
/timer_info_time - Prints a message showing the current time/duration and if the timer is currently active
/timer_info_speed - Prints a message showing the game speed at the start and end of the timer
/timer_set_start_game_speed - The game speed the timer will set at the start of the timer
/timer_set_stop_game_speed - The game speed the timer will set at the end of the timer
