Question : Unix command to search inside files and display results with file date-time

Hi Experts
I want to be able to search inside text files in our HP-UX server for a string. The active shell is ksh.
I am currently using:
find . -type f | xargs grep -l -s "findMe"

This lists the files that I want but I want it to display the files' date and time because the search string is in files on different dates.

I tried the following with no joy:
ll < `find . -type f -print  |xargs grep -l -s "56777"`

Your help is appreciated.

Thanks
Aimee
