Probably. Among the automatic grub-mkrescue options for xorriso's mkisofs emulation is --modification-date=2019042117165600 The equivalent native command is -volume_date uuid 2019042117165600 So you indeed have to override this by an own subsequent command. (SOURCE_DATE_EPOCH overrides defaults of xorriso. But commands or options override the overridden defaults.) Have a nice day :) Thomas
