Do the file timestamps in ISOs matter ?

Hi,
by the narrow margin of one vote, the proposal "set_to_mtime" wins.
Committed as http://libburnia-project.org/changeset/5757
man 1 xorrisofs of the next release will state:
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 --modification-date= and
--gpt_disk_guid. The default of --set_all_file_dates is then
"set_to_mtime".
Startup files and program options can override the effect of
SOURCE_DATE_EPOCH.
This refers to the description of two new options:
--gpt_disk_guid value
Control whether an emerging GPT shall get a randomly generated
disk GUID or whether the GUID is supplied by the user. Value
"random" is default. Value "modification-date" produces a low
quality GUID from the value set by option --modification-date=.
[...]
--set_all_file_dates timestring
[...]
If the timestring is "set_to_mtime", then the atime and ctime of
each file and directory get set to the value found in their
mtime.
[...]
I am now beginning final regression tests for the release of xorriso-1.4.6.
Have a nice day :)
Thomas
