[DataContract]
public class OrderSyncData : ISync
{

    public OrderSyncData(Order o)
    {
        this.CurrentOrderStatus = o.DriverStatus;
        this.StatusDescription = o.StatusDescription;
        SyncTimestamp = o.SyncTimestamp; ????
    }
    [DataMember]
    public string CurrentOrderStatus { get; set; }
    [DataMember]
    public string StatusDescription { get; set; }
    [DataMember]// I don't think I need these any more
    public bool IsCanceled { get; set; }
    [DataMember]
    public bool IsResolved { get; set; }
    [DataMember]
    public bool IsPendingResponse { get; set; }

    DateTime ISync.SyncTimestamp { get; set; }
}

```

How to set the value of ISync.SyncTimestamp? I tried casting the "this." but it doesn't work
