(Go) 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.

    email := chilkat.NewEmail()

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

    // We can also get the Date header like this:
    fmt.Println("Date: ", *email.GetHeaderField("Date"))

    // Load a .eml into the email object:
    success := email.LoadEml("myEmlFiles/someEmail.eml")
    if success != true {
        fmt.Println(email.LastErrorText())
        email.DisposeEmail()
        return
    }

    // Show the Date that was in the .eml
    fmt.Println("Date: ", email.EmailDateStr())

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

    dateTime := chilkat.NewCkDateTime()

    dateTime.SetFromCurrentSystemTime()

    success = email.SetDt(dateTime)
    if success != true {
        fmt.Println(email.LastErrorText())
        email.DisposeEmail()
        dateTime.DisposeCkDateTime()
        return
    }

    // Now show that the Date is the current system time:
    fmt.Println("Date: ", email.EmailDateStr())
    fmt.Println("Date: ", *email.GetHeaderField("Date"))

    email.DisposeEmail()
    dateTime.DisposeCkDateTime()
