The time control is used to tell the user how much time is left for an activity, accurate to seconds.

Var nMS = EndTime-NowTime. getTime ();
// The end time minus the current time to obtain the remaining time
Var nD = Math. floor (nMS/(1000*60*60*24 ));
// Define the parameter to get the number of days
Var nH = Math. floor (nMS/(1000*60*60) % 24;
// Get the hour for defining parameters
Var nM = Math. floor (nMS/(1000*60) % 60;
// Get the defined parameter in minutes
Var nS = Math. floor (nMS/1000) % 60;
