On the other hand, in planetary science we point out that the wherewhen part could not allow description of planetary objects and even may be a problem for satellite position and time description.

Would we get that if we allowed STC to be embedded in WhereWhen? I know we have had arguments about this over the years but I feel that we should be allowed to be pedantically correct in WhereWhen even if we also allow the simplified form.
