That patch was applied in version 2.4-1 and affects all successive versions. libexec/bootstrap-scripts/environment/Makefile.am is patched to call tar with the flag `--mtime="@${SOURCE_DATE_EPOCH:-$(date +%s)}"`, but the dollar sign isn't escaped in the patch, so Make just sees --mtime="@" and substitutes the implausibly old mtime for this invalid one.
