I don't have a config file that does this, but you'll need to the Unix
timestamp in seconds since 1970 as one of the columns in there and use
that.

Do you generate this file all at once for a day or does it get
appended to for each measurement?  If the later, then you can do
something like

group GROUP_NAME1 {
         find_files            filename1 filename2 ...
         column_description    column1_name column2_name ...
         date_source           file_mtime
         interval              3600
         .
         .
         .
         }

where the file_mtime is the important part.

You'll also want to make your measurements at the top of the
hour otherwise RRDtool will interpolate your data to fit at
the top of every hour.

Best,
Blair
