This would break the test case mentioned in D49492, where makefs ignores the time in the mtree file.
If this is the desired behavior, the test should be updated accordingly.

Are you referring to the test case you sketched here? https://reviews.freebsd.org/D49492#1131965

I'm having trouble seeing the problem, given that this revision is intended to apply after D49531 -- could you please explain further?

Originally yes.

I tried applying the entire revision stack, but other tests failed. My main concern was that the test described in https://reviews.freebsd.org/D49492#1131965 was missed, but that is no longer the case. Thank you!

I believe only because they're flagged as being expected to fail, but they no longer fail. I will take a closer look tomorrow.
