This is a derivative of my work[1], and there is no snapshot after Feb 11, 2019[2] making the ${PV} of 0_p20200830 wrong. 1. https://github.com/gentoo/gentoo/tree/master/net-irc/quasselgrep 2. https://github.com/fish-face/quasselgrep/commits/master
I don't know what the "derivative of your work" has to do with this. Anyway, in this case, it's pretty clear that the date is the date the snapshot was taken on, rather than the date of the last commit. There's a mix of styles in the tree.
I was under the impression it's to be tracked with upstream commits for ${PV} for snapshots, but I guess I'm surly incorrect. Sorry for the noise.
as seen in the devmanual[1], under PV it states 'PV Package version (excluding revision, if any), for example 6.3. It should reflect the upstream versioning scheme.'. Is this ignored for upstream where no tags are set, then? 1. https://devmanual.gentoo.org/ebuild-writing/variables/index.html
