Please support Date, Valid-Until when publishing

[bauen1]

Please support Date, Valid-Until when publishing a snapshot or repository.

Detailed Description

See above.

Context

The Date and Valid-Until Fields allow a client to protect itself against replay attacks, source: https://manpages.debian.org/buster/apt/sources.list.5.en.html Or allow Clients to skip downloading the lists if the repository was not updated.

Possible Implementation

Maybe just allow the user to specify the date and valid-until values on the command line would be easy to implement and allow for maximum flexibility (--release-date="", --release-valid-until="")

Your Environment

Using the newest aptly from debian unstable, Version: 1.4.0+ds1-4

And by the way, thank you for this awesome tool, while it has many issues, It's very easy and convenient to use.
