           Summary: Timezones (zoneinfo) starting from October 2014 wrong
                    for Russia, etc
           Product: Base System
           Version: 9.3-RELEASE
          Hardware: Any
                OS: Any
            Status: Needs Triage

The current installed version of FreeBSD 8.4-RELEASE-p16, 9.3-RELEASE-p2 and
10.0-RELEASE-p9 incorrectly convert UTC to/from local time. Differences between
actual zoneinfo IANA and FreeBSD versions [name wrong source file from the
directory contrib/tzdata (share/zoneinfo); country; one of the cities for which
an error has been observed; the near future for which the observed error]:

FreeBSD 8.4-RELEASE-p16:

europe  Russia          Europe/Moscow   (26 Oct 2014)
africa  Egypt           Africa/Cairo    (24 Apr 2015)
        Libya           Africa/Tripoli  (31 Oct 2014)
asia    Palestine       Asia/Hebron     (27 Mar 2015)
        Zion            Asia/Jerusalem  (6 Oct 2014)


FreeBSD 10.0-RELEASE-p9:

europe  Russia          Europe/Moscow   (26 Oct 2014)
africa  Egypt           Africa/Cairo    (24 Apr 2015)


FreeBSD 9.3-RELEASE-p2:

europe  Russia          Europe/Moscow   (26 Oct 2014)


Workarounds:

1. Temporarily use the current version of /usr/ports/misc/zoneinfo (see
attachment zoneinfo-2014.f.txz):
    # portsnap fetch
    # portsnap update
    # cd /usr/ports/misc/zoneinfo
    # make install
    Add WITHOUT_ZONEINFO="yes" to your /etc/src.conf;
    Run tzsetup(8) again to install the right file to /etc/localtime.

2. Copy directory /usr/share/zoneinfo from FreeBSD stable/8, stable/9 or
10.1-RC1.
