3# HOW TO UPDATE THE ZONEINFO DATA
4#
5# Import the new sources to the vendor branch:
6#
7# $ cd ~/freebsd/src
8# $ git worktree add ../tzdata vendor/tzdata
9# $ pushd ../tzdata
10# $ tar -xvf ../tzdata-latest.tar.gz
11#   (check with "git status" and "git diff" if it all makes sense)
12# $ git add -A
13# $ git commit -m "Import tzdata 20XXX"
14# $ git tag -a -m "Tag import of tzdata 20XXX" vendor/tzdata/tzdata20XXX
15# $ git push --follow-tags freebsd vendor/tzdata
16# $ popd
17#
18# Merge-from-vendor
19#
20# $ git subtree merge -P contrib/tzdata vendor/tzdata
21#   (write a meaningful commit message)
22# $ git push freebsd HEAD:main
23#
24# MFC
25#
26# $ git checkout -b freebsd/stable/12 stable-12
27# $ git cherry-pick -x [hash of merge commit to main] -m 1 --edit
28#   (write a meaningful commit message)
29# $ git push freebsd HEAD:stable/12
30#
31#
32# If there are changes to zone1970.tab, update the baseline file by running
33# `make baseline` in usr.sbin/tzsetup to check if tzsetup is able to parse new
34# contents (if not, report/fix tzsetup).  Check that update does not
35# introduce breaking/unexpected changes to continents/countries/zones,
36# and commit the updated baseline file.
