Alternatively, could the build container be adjusted to always begin at 1970-01-01, using =E2=80=98time namespaces=E2=80=99? Linux: https://lwn.net/Articles/766089/ Hurd analogue: https://www.gnu.org/software/hurd/gnumach-doc/Host-Interface= .html#Host-Interface (Of course, someone needs to find the time to write the patches first. May= be I'll have a try at it eventually, but probably not anytime soon.) Also, is there any particular reason to set the clock only ten years ahead, and not, say, a millenia or two? Some possible reasons: * year 2038,2446 problem: the ext2 and ext4 filesystems have a restricted date range * year 2038 problem: https://www.gnu.org/software/hurd/gnumach-doc/Host-Int= erface.html#Host-Interface IMO, the year 2038 problem is a bug and affected packages should simply b= e fixed. But perhaps reality is a little more complicated.
