I’m not concerned with the time, but I get the build date as an NSDate with 
this method:

- (NSDate*) buildDate
{
    NSString* dateStr = [NSString stringWithUTF8String: __DATE__];
    NSDateFormatter* dater = [[NSDateFormatter alloc] init];
    NSLocale *enUSPOSIXLocale = [[NSLocale alloc] 
initWithLocaleIdentifier:@"en_US_POSIX"];
    
    [dater setLocale:enUSPOSIXLocale];
    [dater setDateFormat:@"MMM dd yyyy"];
    NSDate* date = [dater dateFromString: dateStr];
    return date;
}
