Frequent missing publishedAt element for versions where default = true

[vica-atlassian]

We have observed many responses the default version does not have a publishedAt element present.
Eg:
curl https://api.deps.dev/v3alpha/systems/maven/packages/org.hdrhistogram:HdrHistogram/versions/2.2.1 | jq .

Shows publishedAt for all versions, except the 2.2.1 which is the default version.

Hello, thanks for letting us know.

There are some challenges collecting Maven timestamps. We currently collect what we can from the Maven central index files (https://repo.maven.apache.org/maven2/.index/), but those are only updated once a week so it can take a while for the timestamps to fill in and I am aware of a couple of other issues which could slow them down even further.

I do have some work in progress to try and improve the situation by also collecting some other sources of timestamps, so hopefully the situation will improve over the next few months.
