Is there a way to dump timing reports to a file?

Actually I would like to create timing reports from the *.sdc file since I use a perl file to do my build. The perl file basically creates a time stamp used in a version register then calls "quartus_sh" which does the build.

There are a bunch of "tcl" commands such as "report_timing" but they can not be used in an sdc file. They need to be called from the GUI as tcl scripts. I just want to automate the process and having *.sdc calls to create timing reports seems like it would be the easiest.

So are there equivalent *.sdc commands to generate timing reports?

If not, what is the best way to automate the generation of timing reports.
