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. Objective-C

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

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"]);
