bug#75682: ls -l sometimes shows a year in place of the hour and minute

[Bruno Haible via GNU coreutils Bug Reports]

Please give more details:
  - What's the result of
      df -T .
  - What's your libc version?
  - What's the result of
      uname -sr
  - What's the result of
      ls --version

I'm asking because three possible causes come to mind:
  - a network file system (mentioned by Paul Eggert),
  - the multi-grain time stamps introduced in Linux 6.13 [1],
  - a known glibc bug [2] that affects certain coreutils releases.
