//  Once we have the CkDateTime object, we can get the date/time in many different formats:

//  Get as a RFC822 GMT string:
BOOL bLocalTime = NO;

//  Get as an RFC822 string in the local timezone.
//  (remember, the daylight savings that existed at the given time in the past is applied)
bLocalTime = YES;
NSLog(@"%@",[dtTime GetAsRfc822: bLocalTime]);

//  Get as a 32-bit UNIX time (local or GMT..)
//  The Unix time is number of seconds since the Epoch, 1970-01-01 00:00:00 +0000 (UTC). 
int unixTime = [dtTime GetAsUnixTime: bLocalTime];
NSLog(@"%@%d",@"Unix time: ",unixTime);

//  One can also get the as a "DtObj" object for accessing the individual
//  parts of the date/time, such as month, day, year, hour, minute, etc.
//  The DtObj can be obtained in the GMT or local timezone:
CkoDtObj *dtObj = [[CkoDtObj alloc] init];
[dtTime ToDtObj: bLocalTime dtObj: dtObj];
