Should the flag instead be --creation-time?

Phew! Finally green...

jromero

Two minor points:

We should probably cary the term CreationTime across the entire code base instead of having an ambiguous DateTime
Isn't this variable only respected on newer Platform API versions? If so, it seems like we should only be passing it to the container in those cases and warning the user if it's not applicable.

Overall, as always, beautiful! just a few tweaks would be awesome

The tests are green but I don't understand why - https://github.com/buildpacks/pack/runs/6009113466?check_suite_focus=true uses a lifecycle that doesn't support this feature. Investigating.

Fantastic!

This test could actually run in all compatibility cases, but I'm not sure whether it's worth the time cost of having the tests do that.

I found the issue - fixed in c23e970 (it was a bad assertion).
