I also use `{{.StartsAt.Add -600000000000.Unix}}000`. I think we can close this issue.

still valid

Can you please explain more about your issue?

What is the performance cost of this change?

`clear()` is indeed not intended for metrics without labels. You could use e.g. `.set(-1)` if your tests

Thanks!

cc @csmarchbanks @cstyan, do you have some input for this issue?

In general the v1 documentation is under "querying" and it contains much more than querying (e.g. lifecycle). I guess some re-org could be done.

Do we really want to depend on stdlib?

LGTM, but I would prefer to see this behind a flag
