The value MUST conform to the offset portion of xs:dateTime, e.g. -08:00. Note that this value MAY change over time due to daylight saving time, and is thus meant to signify only the current value of the user's timezone offset. > " > > [1] http://member.openmobilealliance.org/ftp/Public_documents/COM/COM-CAB/Permanent_documents/OMA-TS-CAB_XDMS-V1_0-20101019-C.zip > > [2] http://portablecontacts.net/draft-spec.html > > My take is that all the specs are talking about the same representation (i.e. offset from UTC and [+-][0..9][0..9]:[0..9][0..9]) which is what we say in the spec at the moment.

We should at least be clear in the spec when we're talking about timezone and when we're talking about utcoffset. VCard (and CAB) can represent both, separately.
