You're missing a pointer. 

  NSString * update_time= @"2012-03-09 14:54:30.0";

// convert to date
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];

[dateFormat setDateFormat:@"YYYY-MM-dd HH:mm:ss'.0'"];
[dateFormat setTimeZone:[NSTimeZone timeZoneWithName:@"GMT+4"]];
NSDate *dte = [dateFormat dateFromString:update_time ];
NSLog(@"Date: %@", dte);

"GMT+4" is not a valid timzone name. Use timeZoneForSecondsFromGMT: instead:

//...
NSTimeZone *timeZone = [NSTimeZone timeZoneForSecondsFromGMT:4 * (60 * 60)];
[dateFormat setTimeZone:timeZone];
//...

If you want to use timeZoneWithName:, you can get a list of valid timezone names using [NSTimeZone knownTimeZoneNames]. Those all have the form "Europe/Berlin" etc.
