Sorry my bad. I did not read "from remote windows machine on linux?"
Well, I've never done this. In fact I've never even connected from a windows to windows from command line.
I assume telnet works?
have you tried:
telnet <machine> <<EO_MY_INPUT >> output_of_telnet_session.txt
date /t (or whichever is the command to get date/time)
You should have the output in output_of_telnet_session.txt, which you can parse using std linux stuff, grep, sed, awk,...
If you have password-less authentication setup, skip the password on line 2.
