I took JLM's comments as "can't be used by amanda".

If dump won't record/read /etc/dumpdates when dumping
a subdirectory, incrementals will be a real problem.

Not sure if it is used, but gnutar has a similar -N (--newer-mtime)
option.  But if it is based on "mtime" as the option name suggests,
then changes to the inode would be missed.

Ufsdump doesn't have a time-based option.
