    Example
    64-bit Integer field
    FieldDescription bigIntegerFieldDescription = new FieldDescription("BigInteger_64", FieldType.BigInteger);
    
    ObjectID field
    // 64-bit
    FieldDescription oidFieldDescription_64 = new FieldDescription("ObjectID_64", FieldType.OID)
    {
      Length = 8
    };
    
    // 32-bit
    FieldDescription oidFieldDescription_32 = new FieldDescription("ObjectID_32", FieldType.OID)
    {
      Length = 4
    };
    
    DateOnly, TimeOnly, and TimestampOffset field
    // Earthquake occurrences date and time
    
    // 9/28/2014 (DateOnly)
    FieldDescription earthquakeDateOnlyFieldDescription = new FieldDescription("Earthquake_DateOnly", FieldType.DateOnly);
    
    // 1:16:42 AM (TimeOnly)
    FieldDescription earthquakeTimeOnlyFieldDescription = new FieldDescription("Earthquake_TimeOnly", FieldType.TimeOnly);
    
    // 9/28/2014 1:16:42.000 AM -09:00 (Timestamp with Offset)
