# qhelpgenerator stamps CreationTime/LastRegisterTime and the per-file
# TimeStamp into the embedded Qt Help collection (manual-en_US.qhc), which is
# zstd-compressed into the binary's .rodata. It only honors SOURCE_DATE_EPOCH,
# so unless that is pinned, every build bakes in a different wall-clock time
# and the resulting binary (and thus the whole .deb) differs between builds.
#
# We always pass the package's own changelog timestamp below (the same value
# dpkg-buildpackage computes) and override any value the build environment may
# have pre-set: rebuild systems may export a different SOURCE_DATE_EPOCH (e.g.
# their own build timestamp), which would otherwise be baked into the .qhc and
# change the whole binary. The ?= export below covers the rest of the build.
