func chilkatTest() {
    let email = CkoEmail()!

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

        return

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

    // Get as a RFC822 GMT string:
    var bLocalTime: Bool = false
    print("\(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
    print("\(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). 
    var unixTime: Int = dtTime!.getAsUnixTime(bLocalTime)
    print("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:
    var dtObj: CkoDtObj? = dtTime!.getDtObj(bLocalTime)
    if dtTime!.lastMethodSuccess == false {
        print("This should never really happen!")
        return
    }

    print("\(dtObj!.day.intValue)-\(dtObj!.month.intValue)-\(dtObj!.year.intValue) \(dtObj!.hour.intValue):\(dtObj!.minute.intValue):\(dtObj!.second.intValue)")

    dtObj = nil
    dtTime = nil
