I am having an issue where the timestamps for the files in the ipkg have the current timestamp instead of the reproducible timestamp coming from SOURCE_DATE_EPOCH.
I added a debug log message to ptxd_install_fixup_timestamps() found in scripts/lib/ptxd_make_xpkg_pkg.sh to show the timestamp being used:

ptxd_install_fixup_timestamps() {
local timestamp="@${SOURCE_DATE_EPOCH}"
local touch_args
if touch --help | grep -q -- --no-dereference &> /dev/null; then
touch_args="--no-dereference"
fi

echo "ptxd_install_fixup_timestamps ${timestamp} ($(date --date=${timestamp}))"
find "${1}" -print0 | xargs -0 touch ${touch_args} -c -d "${timestamp}"
}

I am currently using ptxdist-2019.11.0, and I get the expected result when directly printing SOURCE_DATE_EPOCH:
$ ptxdist print SOURCE_DATE_EPOCH
1572566400
$ date --date=@$(ptxdist print SOURCE_DATE_EPOCH)
Fri Nov 1 00:00:00 UTC 2019

However, the debug output I added to ptxd_install_fixup_timestamps() produces this output that corresponds to the current datetime:
ptxd_install_fixup_timestamps @1587399767 (Mon Apr 20 16:22:47 UTC 2020)

Ok... I found that this behavior is being caused by this code in ptxd_make_world_init():

#
# check if we shall use a local work-in-progress tree instead
# of the configured URL.
#
# If a link in local_src/<label>.<platform> exists and points to
# a directory, use this instead of the real one.
#
local wip_sources="${PTXDIST_WORKSPACE}/local_src/${pkg_label}${PTXDIST_PLATFORMSUFFIX}"
if [ -d "$(readlink -f "${wip_sources}")" ]; then
pkg_url="file://${wip_sources}"
unset pkg_src
# always use a new timestamp for wip builds
SOURCE_DATE_EPOCH="$(echo $(date "+%s"))"
fi

I would like to have a way to conditionally not set SOURCE_DATE_EPOCH in this case. Suggestions anyone?
