I have an editorial comment and a tiny technical proposal.

Editorial comment

In my understanding, our subsetting is similar to what W3C XML Schema
Part 2, W3C Date and Time Formats (technical note), RFC 3339 (Date and 
Time on the Internet: Timestamps) are doing.  The only significant
difference is that our subset does not have timezone, since no
well-known spreadsheet implementations provide timezone.  If this is the 
case, why don't we say so in the beginning of this draft?


Tiny technical proposal

I am wondering if we should append "Z" always as the last character when 
we specify time information.  RFC 3339 mandates "Z" or explicit timezone.  
RFC 4287 (The Atom Syndication Format), which uses RFC 3339, does the 
same thing.  The following three lines are extracted from RFC 3339.

 date-time       = full-date "T" full-time
 full-time       = partial-time time-offset
 time-offset     = "Z" / time-numoffset
