|
|
# To prepare an update for a new Go release,
|
|
# consult https://www.iana.org/time-zones for the latest versions,
|
|
# update CODE and DATA below, and then run
|
|
#
|
|
# ./update.bash -commit
|
|
#
|
|
# That will prepare the files and create the commit.

#
|

# To review such a commit (as the reviewer), use:
|
|
#
|
|
# git codereview change NNNNNN # CL number
|
|
# cd lib/time
|
|
# ./update.bash
|
|
#
|
|
# If it prints "No updates needed.", then the generated files
|
|
# in the CL match the update.bash in the CL.

# Versions to use.
