Be sure to check out the links Vagrant posted. Specifically this one: https://bugs.debian.org/783938 In that bug report, Samuel Thibault says: "Perhaps javadoc could be made to use by default the SOURCE_DATE_EPOCH environment variable when it is defined?" There seems to be agreement that teaching javadoc to honor the SOURCE_DATE_EPOCH environment variable would be preferable to unconditionally disabling the timestamp behavior. -- Chris
