Question

So I have the following code:

 NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
    [dateFormat setDateFormat:@"MM/dd/yyyy hh:mma"];
    NSString *dateString = [dateFormat stringFromDate:self.firstUsed];
 NSLog(@"FIRST USED %@ %f", dateString, [[NSDate date] timeIntervalSinceDate:self.firstUsed]);

FIRST USED 06/15/2012 10:42PM 716.087895

The thing that confuse me is that when I put in 173.755023 it doesn’t translate back to June 15th 2012 10:42. How is this possible? I think the correct number should be 1339714440

Try this :

NSDate* referenceDate = [NSDate dateWithTimeIntervalSince1970: 0];
NSTimeZone* timeZone = [NSTimeZone timeZoneWithName:@"GMT"];
int offset = [timeZone secondsFromGMTForDate: referenceDate];
int unix_timestamp =  [curdate timeIntervalSince1970];
int Timestamp = unix_timestamp - offset;
