Infinite loop on events due to inacurracy between seconds and miliseconds ?

See original GitHub issue

My bot has been stuck reposting the same event over and over. From my investigation, I’m surprised the problem didn’t seem to emerge earlier and I don’t totally get it.

curl 'https://api.opensea.io/api/v1/events?collection_slug=cryptocubes&occurred_after=1645787316' -H 'Accept: application/json' -H "X-API-KEY: $API_KEY" | jq '.asset_events[-1]'

The returned event created_date is 2022-02-25T11:08:36.706701 Now if we make a moment out of it, we get

> const moment = require('moment');
> moment("2022-02-25T11:08:36.706701").unix()
1645787316

The resulting request will be https://api.opensea.io/api/v1/events?collection_slug=cryptocubes&occurred_after=1645787316 again, and that will fetch and post the same event again. Just incrementing the timestamp by 1 will prevent the problem to happen (but we might miss some events !)

Am I the only one experiencing the problem ? Was occured_after exclusive of timestamp and became inclusive ?
