Then I thought my Contact card is a reasonable place to keep this. So:

Internet Engineering Task Force (IETF)                      S. Perreault
Request for Comments: 6350                                      Viagenie
                        vCard Format Specification
6.5.1.  TZ
    Purpose:  To specify information related to the time zone of the
       object the vCard represents.
    Special notes:  It is expected that names from the public-domain
       Olson database [TZ-DB] will be used, but this is not a
       restriction.  See also [IANA-TZ].

A deprecated interface

      TZ:Raleigh/North America
And an incorrect example.

How does one correct an RFC?  Who should do it?

Wikipedia does a little better:
TZ  Optional  The time zone of the vCard object.  `2.1, 3.0: TZ:-0500
                                                    4.0: TZ:America/New_York
