c# - Datetime Timer Interval does not change speed of months added - 


datetime newdate = new datetime(2013, 1, 1);  void addtime() {     timer1.interval = 600000;      timer1.enabled = true;    timer1.tick += new eventhandler(timer1_tick);    timer1.start(); } void timer1_tick(object sender, eventargs e) {     newdate = newdate.addmonths(+3);     lbldate.text = newdate.tostring();  }

for reason changing timer1.interval not change speed of 3 months being added newdate, constant. trying have 1 minute real life time equal 3 months in game. using c#.

your initial timer interval bit larger. below sample complete application. working expected 

using system; using system.windows.forms;  namespace windowsformsapplication1 {     public partial class form1 : form     {         datetime newdate = new datetime(2013, 1, 1);         public form1()         {             initializecomponent();             addtime(); // call method, otherwise timer not start          }         void addtime()         {             timer1.interval = 60000; // every minute (1 minute = 60000 milliseconds)             timer1.enabled = true;             timer1.tick += new eventhandler(timer1_tick);             timer1.start();         }         void timer1_tick(object sender, eventargs e)         {             newdate = newdate.addmonths(3);              label1.text = newdate.tostring();         }         // if need set timet interval after timer start, below          private void button1_click(object sender, eventargs e)         {             timer1.stop();             timer1.interval = 30000; // set interval 30 seconds              timer1.start();         }     } }
