TS is a string representation using standard notation of a point in time. This is implemented in the LRA as specified in ISO
21090. As with QTY both uncertainty and uncertaintyType within this data type are difficult to distinguish from uncertainty
represented by URG and UVL., and from an LRA implementation perspective where they are required, it is believed they should
be managed as specifically stated uncertain dates or ranges. These constraints on uncertainty are present in the LRA profile
of QTY and not formally restated here. Otherwise this class and its constraints are used as represented in ISO 21090.
This is implemented as described in ISO 21090.
