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. Swift

func chilkatTest() {
    var success: Bool = false

    let email = CkoEmail()!

    // At this point, a new email object has been instantiated, and it
    // already has a Date header field containing the current date/time.
    print("Date: \(email.emailDateStr!)")

    // We can also get the Date header like this:
    print("Date: \(email.getHeaderField(fieldName: "Date")!)")

    // Load a .eml into the email object:
    success = email.loadEml(mimePath: "myEmlFiles/someEmail.eml")
    if success != true {
        print("\(email.lastErrorText!)")
        return
    }

    // Show the Date that was in the .eml
    print("Date: \(email.emailDateStr!)")

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

    let dateTime = CkoDateTime()!

    dateTime.setFromCurrentSystemTime()

    success = email.setDt(dt: dateTime)
    if success != true {
        print("\(email.lastErrorText!)")
        return
    }

    // Now show that the Date is the current system time:
    print("Date: \(email.emailDateStr!)")
    print("Date: \(email.getHeaderField(fieldName: "Date")!)")
