Hello again,

Here a session of a backup archive is written to a DVD.

xorriso -for_backup -dev /dev/sr0 \
  -update_r . / \
  -commit \
  -toc -check_md5 failure -- \
  -eject all
 
This command gives the contents of a DVD.
  xorriso -dev /dev/sr0 -toc

TOC layout   : Idx ,  sbsector ,       Size , Volume Id
ISO session  :   1 ,         0 ,    678303s , ISOIMAGE
ISO session  :   2 ,    716368 ,     13376s , ISOIMAGE
ISO session  :   3 ,    737600 ,    816699s , ISOIMAGE
  ...

Session time stamps would help when recovering from a 
storage failure.  Eg.

Date        TOC layout   : Idx ,  sbsector ,       Size , Volume Id
2023-07-23  ISO session  :   1 ,         0 ,    678303s , ISOIMAGE
2023-07-29  ISO session  :   2 ,    716368 ,     13376s , ISOIMAGE
2023-08-06  ISO session  :   3 ,    737600 ,    816699s , ISOIMAGE

Can the current xorriso include session timestamps?  In the manual I 
see file timestamps mentioned.  Not session timestamps.

Thx,                                   ... P.
