Looks much like a ISO 9660 filesystem timestamp: 2015053119211000
GRUB2 would make this from Modification Date.

So try in -as mkisofs emulation:


or in native xorriso command mode

  -volume_date uuid 2015060515051200

The bad news is that you have few freedom of expression with
these strings. They have to be valid time strings of the form
YYYYMMDDhhmmsscc. That's because their main job is to give
the ISO filesystem production data.

You may inquire the timestamps of an existing ISO by xorriso.

  xorriso -indev debian-7.7.0-amd64-netinst.iso -pvd_info

reports among other lines

  Creation Time: 2014101813055400
  Modif. Time  : 2014101813055400

Have a nice day :)
