#import <CkoEmail.h>
#import <CkoDateTime.h>
#import <CkoDtObj.h>

CkoEmail *email = [[CkoEmail alloc] init];

// Load a .eml file into the email object.
BOOL success = [email LoadEml: @"/home/users/chilkat/eml/myEml.eml"];

CkoDateTime *dtTime = [email GetDt];
if (email.LastMethodSuccess == NO) {
    NSLog(@"%@",@"Email has no Date header field.");
    return;
}

// Once we have the CkDateTime object, we can get the date/time in all sorts of formats:

// Get as a RFC822 GMT string:
BOOL bLocalTime = NO;
NSLog(@"%@",[dtTime GetAsRfc822: bLocalTime]);

// 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 = [dtTime GetDtObj: bLocalTime];
if (dtTime.LastMethodSuccess == NO) {
    NSLog(@"%@",@"This should never really happen!");
    return;
}

NSLog(@"%d%@%d%@%d%@%d%@%d%@%d",[dtObj.Day intValue],@"-",[dtObj.Month intValue],@"-",[dtObj.Year intValue],@" "
    ,[dtObj.Hour intValue],@":",[dtObj.Minute intValue],@":",[dtObj.Second intValue]);
