Hey Wilfred!

 WvV> But that's not the TZUTC flag. ;)

I forgot to turn them both on in the last reply.  Let me know if it actually
makes a difference.  Also I took the liberty of dropping the ':' character
between hours and minutes in the TZ part of the RFC-3339 flag which now
perfectly matches the digits in the TZUTC flag.  It makes no difference to it's
enhanced usage over the both the MSG header datetime stamp with the TZUTC and
vastly eliminates much code in order to make TZUTC useful.

That's my story and I am sticking to it.

Life is good,
Maurice
