date problem while adding Event to iPhone calendar -

while adding event calendar of iphone, date going reseted 1.1.2001 , have no idea why.

id arg1 = [args objectatindex:0];  // start id arg2 = [args objectatindex:1];  // end id arg3 = [args objectatindex:2];  // title id arg4 = [args objectatindex:3];  // location id arg5 = [args objectatindex:4];  // text  nsdateformatter *df = [[nsdateformatter alloc] init]; [df setdateformat:@"yyyy-mm-dd hh:mm:ss"]; nsdate *startdate = [df datefromstring: arg1]; nsdate *enddate = [df datefromstring: arg2];  ekeventstore *eventstore = [[[ekeventstore alloc] init] autorelease];  ekevent *event  = [ekevent eventwitheventstore:eventstore];  event.title     = arg3; event.location  = arg4; event.notes     = arg5; event.startdate = startdate; event.enddate   = enddate;    [event setcalendar:[eventstore defaultcalendarfornewevents]]; nserror *err; [eventstore saveevent:event span:ekspanthisevent error:&err]; 

the input seems fine since

nslog([args objectatindex:0]); 

writes correct date. have no real idea :(

your input maybe correct formatter not. please, review these 2 lines. believe bug there

[df setdateformat:@"yyyy-mm-dd hh:mm:ss"]; nsdate *startdate = [df datefromstring: arg1];
