"Wheel has unexpected file name" with timestamp in dynamic version

[dseomn]

Description

From pypa/setuptools-scm#1099, when the version is generated dynamically and includes the timestamp, pip fails when the timstamp changes.

Expected behavior

No error when the version includes the timestamp. Maybe that means freezing the version at the beginning, or maybe changing the validation logic, I'm not sure.

pip version

25.1.1

Python version

3.13.3

OS

Debian testing/unstable

How to Reproduce

See pypa/setuptools-scm#1099. Basically, use setuptools_scm's local_scheme = "node-and-timestamp" to include the timestamp in the version.

Output

From pypa/setuptools-scm#1099:

This one is tricky as it presumes certain details

I wonder if its necessary to consider ctime in setuptools_scm

[pfmoore]

It sounds to me like prepare_metadata_for_build_wheel might be returning a different version than build_wheel - which could be because the version is based on a time (the resolver can take multiple seconds to complete). If that's the case, then it's likely a build backend error, as build_wheel is supposed to respect the metadata directory passed into it (which will have come from prepare_metadata_for_build_wheel).

[RonnyPfannschmidt]

So setuptools_scm needs to ensure its the same

Setuptools doesn't expose the details in any way it can act uppon
