From d157a76c67bcb821d3ec8dcd4312390ef129a95a Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Thu, 8 Nov 2018 11:52:33 +0100 Subject: [PATCH] script: ipkg-build: honour $SOURCE_DATE_EPOCH When the SOURCE_DATE_EPOCH environment variable is set, use it to override the timestamps of .ipk archive contents. This ensures that .ipk archives built in environments without SCM metadata (mainly the SDK) are reproducible between different runs.
