In older versions of Ubuntu, like 9.10,
ls(1) produced ISO 8601 format by default, in the way
ls -l --time-style=long-iso
does it. With 12.04, we're back at the older Unix style. Thus replacing the year by minutes and seconds for recent dates.
How can I - in the least intrusive manner change this back to
long-iso? Is there maybe some general configuration option?
