In the command line, how do I add the datetime into the output file name?

$ cat some_file.txt | grep some_search_term > output_file_[datetime_stamp].txt

Thanks,

$ cat some_file.txt | grep some_search_term > output_file_`date +%Y+m%d-%H%M`.txt
where
   date +%Y+m%d-%H%M
  gives the time stamp output format as   20110903-1020

do
  man date
   for more details.
