Bug description:
  [IMPACT]

  uptime will provide incorrect data after 52 weeks. This is at least confusing for users utilizing this tool.
  Issue is already fixed in upstream https://gitlab.com/procps-ng/procps/-/commit/8827c6763f79f77a126968e200b0e402de7cb749.
  Latest procps releases already include this patch (procps 4.0.3 lunar/mantic)
  The fix is needed for following set of packages:
  procps | 2:3.3.17-6ubuntu2   | jammy
  procps | 2:3.3.16-1ubuntu2   | focal

  [TEST CASE]

  UPTIME="31528920 31528800"; mkfifo uptime_fifo; while true; do cat <<<$UPTIME > uptime_fifo; done & sudo mount -obind uptime_fifo /proc/uptime
  uptime -p
  Running above commands will result in incorrect uptime output.

  [REGRESSION POTENTIAL]

  The patch is already available in upstream, lunar/mantic releases
  already include is as well.
