From 34271d38ae9087816219de0bf9ff5197483277e6 Mon Sep 17 00:00:00 2001 From: Sander Vanheule Date: Thu, 6 Aug 2020 22:10:32 +0200 Subject: [PATCH] tools/firmware-utils: use UTC for image timestamps By using localtime() to determine the timestamp that goes into factory images, the resulting image depends on the timezone of the build system. Use gmtime() instead, which results in more reproducible images.
