Customize time format of 'ls -l'

ls -l --time-style=+"%Y-%m-%d %H:%M:%S"
the --time-style argument to 'ls' takes several possible modifiers: full-iso, long-iso, iso, locale, +FORMAT. The +FORMAT modifier uses the same syntax as date +FORMAT. --time-style=+"%Y-%m-%d %H:%M:%S" strikes a happy medium between accuracy and verbosity: ls -lart --time-style=long-iso doesn't show time down to the nearest second, ls -lart --time-style=full-iso displays time to 10E-9 second resolution, but with no significant digits past the full seconds, also showing the timezone: -rw-r--r-- 1 bchittenden bchittenden 0 2011-02-10 12:07:55.000000000 -0500 bar
Sample Output
$ ls -lart --time-style=+"%Y-%m-%d %H:%M:%S" demoroniser.1 bar
-rw-r--r-- 1 bchittenden bchittenden 6723 2003-09-16 08:44:30 demoroniser.1
-rw-r--r-- 1 bchittenden bchittenden    0 2011-02-10 12:07:55 bar

I prefer +"%Y-%m-%d %H:%M:%S" format because the dates will collate correctly when you do a standard unix sort... granted, ls will sort by date for you, but I'm used to displaying dates in that format for that reason.
