Question

I using CoreData to store my objects that I fetch from a server.

I have a failure somewhere and cannot figure out what is going wrong. But it looks like it is related to the date stored in the CoreData database. So I opened the sqllite database and tried to compare the dates but since they are, for me, not human readable, is there any way to convert a serialized NSDate back into a human-readable date? (year-month-day for example)

I have the following dates in the CoreData database.
How can I convert them back into a human-readable date format? An online converted would be great since it is very difficult to write just an app for that.

Thanks and regards.

They are simply timestamps since interval reference date. Here’s code you can use to decode them:

NSNumber *time = [NSNumber numberWithDouble:(d - 3600)];
NSTimeInterval interval = [time doubleValue];    
NSDate *online = [NSDate dateWithTimeIntervalSinceReferenceDate:interval];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"MM/dd/yyyy HH:mm:ss.SSS"];

NSLog(@"result: %@", [dateFormatter stringFromDate:online]);
