    // Let's say we have a timestamp string such as 2016-11-11T14:32:17.0908971Z
    var strTimestamp: String? = "2016-11-11T14:32:17.0908971Z"

    let dateTime = CkoDateTime()
    dateTime.SetFromTimestamp(strTimestamp)

    // Get a DtObj in the local timezone.
    var bLocalTimezone: Bool = true
    var dt: CkoDtObj? = dateTime.GetDtObj(bLocalTimezone)
