Set the Email Date Header to the Current System Date/Time

Demonstrates how to set the Date header field of an email to the computer's current date/time. Note: When an email object is instantiated, the Date header field is automatically added and initialized to the current system date/time. The need to explicitly set the Date header could arise when loading an email from a .eml.

BOOL success = NO;

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

//  At this point, a new email object has been instantiated, and it
//  already has a Date header field containing the current date/time.
NSLog(@"%@%@",@"Date: ",email.EmailDateStr);

//  We can also get the Date header like this:
NSLog(@"%@%@",@"Date: ",[email GetHeaderField: @"Date"]);

//  Load a .eml into the email object:
success = [email LoadEml: @"myEmlFiles/someEmail.eml"];
if (success != YES) {
    NSLog(@"%@",email.LastErrorText);
    return;
}

//  Show the Date that was in the .eml
NSLog(@"%@%@",@"Date: ",email.EmailDateStr);

//  Now the Date header contains whatever was in the .eml
//  Let's update it to the current system date/time..

CkoDateTime *dateTime = [[CkoDateTime alloc] init];

[dateTime SetFromCurrentSystemTime];

success = [email SetDt: dateTime];
if (success != YES) {
    NSLog(@"%@",email.LastErrorText);
    return;
}

//  Now show that the Date is the current system time:
NSLog(@"%@%@",@"Date: ",email.EmailDateStr);
NSLog(@"%@%@",@"Date: ",[email GetHeaderField: @"Date"]);
