SOURCE_DATE_EPOCH belongs to the specs of reproducible-builds.org. It
is supposed to be either undefined or to contain a decimal number which
tells the seconds since january 1st 1970. If it contains a number, then
it is used as time value to set the default of -volume date "uuid", sets
-boot_image "any" "gpt_disk_guid=" to "volume_date_uuid", and
-volume_date "all_file_dates" to "set_to_mtime",
Startup files and program options can override the effect of
SOURCE_DATE_EPOCH.
