Grab "date Modified" info from file?

[#1]

So I've been handed an old .jsl file that parses a bunch of .dat and .csv files into a combined .jmp table.  It looks through several files for each lot (one per wafer) and combines it all into a single data table.  However, it was never programmed to add the timestamp from the metro tool.  How can I add to the .jsl to grab the timestamps from the files?

Any help please?

see if the Last Modification Date function returns the information you need.  From the scripting index:

Format(
  Last Modification Date(
  "$SAMPLE_DATA/Big Class.jmp"
  ),
  "ddmonyyyy:h:m:s"
);

"30Jan2015:13:50:52"

edit: or the Creation Date function.
