Hmm. I am not sure about this, as it is quite possible that time values
will be changing as UNIX moves to a 64-bit number. Also, MySQL could
easily change the length of the return value, and it may even change
based on locale or other settings.

However, I am willing to look at something that can reliably detect
an iso time and do something with it. Any suggestions from the 
group?
