Section 10.2 says:
[TZDB] Eggert, P. and A.D. Olson, "Sources for Time Zone and Daylight Saving Time Data", July 2009, <http://www.twinsun.com/tz/tz-link.htm>.
It should say:
[TZDB] Eggert, P. and A. Olson, "Sources for Time Zone and Daylight Saving Time Data", 1987, <ftp://ftp.iana.org/tz/code/tz-link.htm>. Internet Assigned Numbers Authority (IANA) "Time Zone Database" <http://www.iana.org/time-zones>.
The twinsun.com version is no longer maintained by the volunteer(s) email@example.com. The document and the tz database, have been adopted by members of IETF and iana.org. The database itself is public domain.
The corrected text matches that of rfc6557 11.1. Normative References [TZDB]
The document was correct at the time it was published, so this report does not meet the formal criteria for errata.
That said, Peter is correct that the location of the time zone database has since changed, and readers should look to the new location, as he has specified in this report.
