+Subject: [PATCH] Use SOURCE_DATE_EPOCH to render dates in template.
+
+Whilst working on the Reproducible Builds effort [0], we noticed
+that grunt can generate non-reproducible output. This is affecting the
+reproducibility status other packages (such as jquery-tablesorter) that
+set a "pkg.banner" such as:
+
+   <%= grunt.template.today("mm-dd-yyyy")
