    email := chilkat.NewEmail()

    // Load a .eml file into the email object.
    success := email.LoadEml("/home/users/chilkat/eml/myEml.eml")

    dtTime := email.GetDt()
    if email.LastMethodSuccess() == false {
        fmt.Println("Email has no Date header field.")
        email.DisposeEmail()
        return
    }

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

    // Get as a RFC822 GMT string:
    bLocalTime := false
    fmt.Println(*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 = true
    fmt.Println(*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). 
    unixTime := dtTime.GetAsUnixTime(bLocalTime)
    fmt.Println("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:
    dtObj := dtTime.GetDtObj(bLocalTime)
    if dtTime.LastMethodSuccess() == false {
        fmt.Println("This should never really happen!")
        email.DisposeEmail()
        return
    }

    fmt.Println(dtObj.Day(), "-", dtObj.Month(), "-", dtObj.Year(), " ", dtObj.Hour(), ":", dtObj.Minute()
        , ":", dtObj.Second())

    dtObj.DisposeDtObj()
    dtTime.DisposeCkDateTime()
