====== ISO date in ls -l ======

By default, the ls command shows a short and inconsistent date/time column. No year is being displayed if the file is less than a year old. To change this behaviour and always display the full iso date and time, edit ''~/.bashrc'' and adjust or add the ls alias line like so:

<code>
    alias ls='ls --color=auto --time-style=long-iso'
</code>

Then log out and back into the terminal or use the following command to apply the config change:
<code>
source ~/.bashrc
</code>

On other shells, it may have to be added to ''.profile''. If an alias is not the preferred way, the default time-style can be set using the environment variable ''TIME_STYLE'' either via .bashrc or .profile or system-wide in ''/etc/profile''
<code>
export TIME_STYLE="long-iso"
</code>
