Yes, something like that... RFC3339 has a trick of using -00:00 offset for
4.3. Unknown Local Offset Convention
If the time in UTC is known, but the offset to local time is unknown,
this can be represented with an offset of "-00:00". This differs
semantically from an offset of "Z" or "+00:00", which imply that UTC
is the preferred reference point for the specified time. RFC2822
[IMAIL-UPDATE] describes a similar convention for email.
I don't recall if this is true in ISO 8601 - maybe not.
(I'm not promoting the syntax here, just supporting the general concept.)
