+Description: Allow the build timestamp to be externally set
+ In order to make Ghostscript output reproducible, we need a way to
+ set the build timestamp to other values than the current time.
+ We now consistently use gp_get_realtime() instead of directly calling
+ time() or gp_get_usertime() and make gp_get_realtime() use the value
+ found in the SOURCE_DATE_EPOCH environment variable if set. Also,
+ environment timezone is fixed to UTC if SOURCE_DATE_EPOCH is used to
+ avoid variations.
