perlquestion raiten <p>Hello monks, <p>I'm looking for a way to parse a directory and group files which have a create date (or exif create date) at less than n seconds interval between each other (consecutive files in time) I'm trying to preprocess files to generate a list for hugin panoramic generation. <p>date is in filename (yyyymmdd_hhMM--name) or in exif create date (exiftool). I can extract a primary list because I tagged my files with a keyword but it's not sufficient to get a good output by panostart. So in this list of filenames, I want to find a way to generate sublist of files which have a maximum time interval of n seconds between their datetime (typically 5-10 sec) <p>Any ideas how to do that ? <p> <p>Thanks a lot. Cheers
