This already got sponsored:

So I'm unsubscribing ~ubuntu-sponsors.

I see there are some build-failures for armhf/i386. If further uploads
are needed, please re-subscribe ubuntu-sponsors.

Title:
  faketime doesn't fake stat(1) or ls(1) timestamps after Ubuntu 20.10

Status in faketime package in Ubuntu:
  Fix Committed
Status in faketime package in Debian:
  New

Bug description:
  In all versions of Ubuntu including and after 20.10 (groovy)
  (including 22.04, 23.10, and the current devel release noble), the
  'faketime' package fails to correctly fake timestamps for core
  commands like 'stat' and 'ls'. Instead, the on-disk timestamps are
  returned:

    # LD_PRELOAD=/usr/lib/x86_64-linux-gnu/faketime/libfaketime.so.1 FAKETIME='1970-01-01 00:00:01' stat /
      File: /
      Size: 4096      	Blocks: 8          IO Block: 4096   directory
    Device: 72h/114d	Inode: 14475976    Links: 1
    Access: (0755/drwxr-xr-x)  Uid: (    0/    root)   Gid: (    0/    root)

  In Ubuntu 20.04, or with faketime built from current git master, the
  correct result is returned:

    # LD_PRELOAD=/usr/lib/x86_64-linux-gnu/faketime/libfaketime.so.1 FAKETIME='1970-01-01 00:00:01' stat /
      File: /

  This seems to be related to upstream bug
  https://github.com/wolfcw/libfaketime/issues/417 which was fixed by PR
  https://github.com/wolfcw/libfaketime/pull/434

  Ubuntu directly followed Debian with this bug, it was introduced in
  Debian's bullseye (11) release, with the same command working in
  buster (10).

  Unfortunately, faketime hasn't had a release since the fix for statx
  was merged, so Debian hasn't noticed either.
