timer connected to time limit menu

[addicted 1]

Hello

Is that any possibility to connect custom timer with time limit chosing from parameters menu? In description I have this

class Params
{
class TimeLimit {
	title = "Time limit";
	values[] = {1000000, 30, 180, 900, 1200, 1500, 1800, 2700, 3600, 5400, 7200};
	texts[] = {"Unlimited", "30 sec", "3 min", "15 min", "20 min", "25 min", "30 min", "45 min", "60 min", "90 min", "120 min"};
	default = 3600;
	};

I have my custom timer and I need some command to set starting number in this timer as same as I chosen from parameters menu.
