Bottom post on this mailing list, please.

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.
