It is not clear to me your expectation: - are you asking how to use ctime to select the file with tar alone ? It is not possible for my understanding of the manual.
- Are you asking the package maintainer to change the behaviour of cygwin tar ? Unlikely to happen, but I leave to him. Regards Marco Hi Marco, Sorry, I am new to the mailing list. If I am not wrong, tar is checking both of the ctime and mtime values to compare files during incremental backups. Since opening and closing a MS document without changing the content updates ctime, it would be preferable to add a new option to tar to use only mtime for file comparing during incremental backups.
