Month in Terminal is in Russian - only in Terminal!

For some reason whenever month appears in terminal (e.g. ls -l command) the month is in Russian. No other dates appear in Russian and I've gone into System Preferences -> Language & Text and made sure that Russian is not at the top of the list at all. This problem seems specific to Terminal. Below is the output of ls -l command:

Any ideas?

Please post the result of the command 'env' here (without the quotes).

What language do you want it in? Your LANG environment variable is set to Russian
LANG=ru_RU.UTF-8

If you are looking for english it should be
LANG=en_US.UTF-8


If it is /bin/bash then

Right, check your .dot files. Looks like somewhere it is being changed. Only place I've seen Lang used was in an old .xinitrc file which I don't use anymore but I guess it could be anywhere.
