showing last mod. of *included* file

I have been using this code to show the last modified time: (Note: the following was adapted from http://www.terrabyte.dc.com.au/phpscripts.php3 ) // the server is 13 hours ahead of Eastern Time USA $hourdiff = "13"; $timeadjust = ($hourdiff * 60 * 60); $eastern_time = date("d M Y g:ia",getlastmod() - $timeadjust); echo "Last modified: $eastern_time (ET/USA) <br />"; This works really well, except for one thing. All of my pages have two required parts: index.php body.html and two optional parts header.html footer.html The code above is 'include'd into 'index.php' 'index.php' is a boilerplate, and will hardly ever change. The optional files are not likely to change all that often, if ever, if they exist. Is there a way that I can adapt the above PHP code to show the last mod. time of 'body.html' (always the same filename) instead of index.php? TjL ps -- I did try to Google the solution, but this is such a specific situation (needing to adjust the timestamp and then check the last mod of an included file) that I did not have any luck finding anything that was 'on target'.
