Arnold,

Are you suggesting that we define a new binary table TFORMn data code 
(e.g., 'T') for ISO 8601 date strings?  In this case, I presume the 
repeat count value (as in TFORM1 = '19T') would give the width of the 
single date value, in bytes, and would not mean that the column contains 
a vector of 19 ISO data values.

If this is what is being proposed, then it sounds to me like a major 
change to FITS that should be discussed as a separate proposal, rather 
than including it as part of the current exercise to simply update and 
clarify the wording of the FITS Standard.
