XnView 1.97.x fully supports this date interface: it is possible to insert "uncertain" dates in IPTC DateCreated (data set 2:55) without problems.
XnViewMP 0.26.1 (as tested on WinXP) does not support this interface:
- it is not possible to specify an uncertain date in IPTC DateCreated;
- an existing uncertain date in IPTC DateCreated (as inserted by XnView 1.97) is shown as "01.01.2000" in the IPTC dialog window;
- more serious, the uncertain date will be overwritten by this default date in case another IPTC entry is updated. Obviously, this is a data corruption and an incompatibility to Xnview 1.97.
