   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.
