[bug] created_at and updated_at are in different time zones

nedbat commented 6 months ago

What happened?

Using actions/upload-artifact, I get artifacts with created_at and updated_at in different time zones, but both with a Z suffix.

The action run: https://github.com/nedbat/coveragepy/actions/runs/7276115944/job/19825271579, step Upload coverage data:

The resulting artifact from the REST API:

        "head_sha": "8c85f6783103820ae61d07fe930fc19fa1acbc81"
      }
    }

The created_at time seems to be Pacific time with a Z suffix, while updated_at is GMT. The action was run ten minutes ago, just before 9AM Eastern time.

What did you expect to happen?

The two times should be the same, or at the very least, the time zone suffix in the ISO-8601 format should be correct.

How can we reproduce it?

I don't think I did anything unusual. The workflow step is here: https://github.com/nedbat/coveragepy/blob/8c85f6783103820ae61d07fe930fc19fa1acbc81/.github/workflows/coverage.yml#L102-L106

Anything else we need to know?

This example is Mac OS, but I see the same behavior on all OS's.

What version of the action are you using?

v4

What are your runner environments?

macos

Are you on GitHub Enterprise Server? If so, what version?

No response

👋 @nedbat Thanks for the report. The created_at timestamps for new Artifacts should be correct now.
