REST API - Timestamp of StateChange

Hey people!

Is there any way of accessing the timestamp of an ItemStateChangedEvent via REST API?

Thanks for any advice,

I use the item WolfgangsDevice_LastSeen. It contains the timestamp when my phone last was seen to be online ( the timestamp is being updated as long as it is online ).
As this is a normal item it can be queried via the REST API

curl -X 'GET' \
  'http://pi:8080/rest/items/WolfgangsDevice_LastSeen?recursive=true' \
  -H 'accept: application/json' \
  -H 'Authorization: Bearer 'xxxxxxxxxxxxx...xxxxxxxxxxxxx'

Returned result then looks like:

{"link":"http://pi:8080/rest/items/WolfgangsDevice_LastSeen","state":"2022-03-27T16:15:28.438+0200","stateDescription":{"readOnly":true,"options":[]},"editable":false,"type":"DateTime","name":"WolfgangsDevice_LastSeen","label":"Last Seen","tags":["Point"],"groupNames":["WolfgangsDevice"]}
