Fix EventbridgeClient: send PutEvents Time as a Date (SDK v3)

[billfreeman44]

Problem

EventbridgeClient.putEvents sends the entry Time as an ISO string. Under AWS SDK v3, PutEventsCommand rejects that with:

SerializationException: STRING_VALUE can not be converted to milliseconds since epoch  (HTTP 400)

formatEventInput normalized the event's time to an ISO string and passed it straight through:

evolve({
  detail: toJson,
  time: compose(toIso, fromIsoUtc)   // <- ISO string
})

SDK v2 tolerated a timestamp string; v3 requires a real Date. This is the same class of bug that broke blobd's eventbridge-put-events handler after its v3 migration (fixed there in 3.1.0).

Impact: latent today — no current caller passes a top-level time (event emitters use { detail, detailType, source }), so EventBridge defaults Time to ingestion time. But the moment any event carries a time, it fails. This removes the landmine.

Fix

Wrap the normalized value in a Date so the SDK marshals it correctly:

time: compose((iso) => new Date(iso), toIso, fromIsoUtc)

Normalization via fromIsoUtc/toIso is preserved; only the final type handed to the SDK changes (string → Date).

Validation

• npx ava lib/clients/eventbridge.spec.js → 6/6 pass (spec updated to expect Time: new Date(...)).
• Prettier: content-clean (the local --check warning is the repo's known CRLF-vs-LF false positive; CI runs on LF).

Pull request overview

This PR fixes EventbridgeClient.putEvents for AWS SDK v3 by ensuring the Time field in PutEventsCommand entries is sent as a Date object (not an ISO string), preventing the SDK v3 SerializationException when callers provide an event time.

Changes:

• Update formatEventInput to convert the normalized ISO timestamp into a Date before passing it to the AWS SDK.
• Update the EventBridge client spec to expect Time as a Date.
• Document the fix in CHANGELOG.md (v3.0.3).
