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