-# reproducible_build.bbclass
-#
-# Sets SOURCE_DATE_EPOCH in each component's build environment.
-# Upstream components (generally) respect this environment variable,
-# using it in place of the "current" date and time.
-# See https://reproducible-builds.org/specs/source-date-epoch/
-#
-# After sources are unpacked but before they are patched, we set a reproducible value for SOURCE_DATE_EPOCH.
-# This value should be reproducible for anyone who builds the same revision from the same sources.
-#
-# There are 4 ways we determine SOURCE_DATE_EPOCH:
-#
-# 1. Use the value from __source_date_epoch.txt file if this file exists.
-#    This file was most likely created in the previous build by one of the following methods 2,3,4.
-#    Alternatively, it can be provided by a recipe via SRC_URI.
-#
-# If the file does not exist:
-#
-# 2. If there is a git checkout, use the last git commit timestamp.
-#    Git does not preserve file timestamps on checkout.
-#
-# 3. Use the mtime of "known" files such as NEWS, CHANGLELOG, ...
-#    This works for well-kept repositories distributed via tarball.
-#
-# 4. Use the modification time of the youngest file in the source tree, if there is one.
-#    This will be the newest file from the distribution tarball, if any.
-#
-# 5. Fall back to a fixed timestamp.
-#
-# Once the value of SOURCE_DATE_EPOCH is determined, it is stored in the recipe's SDE_FILE.
-# If none of these mechanisms are suitable, replace the do_deploy_source_date_epoch task
-# with recipe-specific functionality to write the appropriate SOURCE_DATE_EPOCH into the SDE_FILE.
-#
-# If this file is found by other tasks, the value is exported in the SOURCE_DATE_EPOCH variable.
-# SOURCE_DATE_EPOCH is set for all tasks that might use it (do_configure, do_compile, do_package, ...)
