Then I thought my Contact card is a reasonable place to keep this. So:
<https://datatracker.ietf.org/doc/html/rfc6350#section-6.5.1>
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
Examples:
TZ:Raleigh/North America
...
And an incorrect example.
How does one correct an RFC? Who should do it?
Wikipedia does a little better:
<ihttps://en.wikipedia.org/wiki/VCard>
TZ Optional The time zone of the vCard object. `2.1, 3.0: TZ:-0500
4.0: TZ:America/New_York
