'Last updated' field on status.nixos.org does not reflect expected value. about nixos-status

This issue has been mentioned on NixOS Discourse. There might be relevant details there:

As a workaround... the commit date is easy to get locally (should be very close to push date unless people do something "weird"), so I've been now using bash snippet:

	git fetch origin && echo "" && \
	git show --no-patch '--pretty=format:%>(12)%cr  %h %d' \
		origin/nixos-{20.09,unstable}{,-small} \
		origin/nixpkgs-{20.09-darwin,unstable} \
		| grep -vF origin/release-20.09 | grep -vF origin/master \
		| sort --ignore-leading-blanks --key=2,2 --key=1nr,1
	# grep -v: don't even show lines that match the latest *pushed* commits

	# TODO: "2 weeks" and older sort incorrectly! (hours and days are OK)
	# What stamp in --pretty?  %ci  %s

^^ re-EDITed after we dropped support for the nixpkgs-channels repo.

@wamserma is this still the issue? As far as I can see the date is now recorded in Prometheus and that is what status.nixos.org is querying.

I'm closing the issue but please reopen it if I made wrong judgement.

I think this is fine now.

It seems that the currently shown stamp is the moment the channel got published. From my point of view, I prefer the moment when its commit was pushed (to github.com/nixos/nixpkgs).

I can recall cases when they were very far, typically when a channel is blocked. It's when I retrospectively restarted some older transient failures to advance the channel at least a little, even if the corresponding commit is a few days old already – and then status.nixos.org shows the channel as fresh even if it isn't.

Maybe my expectations aren't in majority? Anyway, I keep using my script above...

@vcunat I see no reason why not to have a new column "Last pushed". Feel free to send PR and I'll review it.
