[v2] Different timestamp format on user change

Different timestamp format is sent on user change:

{“data”:{…},“meta”:{“action”:“change” ,“entity”:“user”,“timestamp”:1680259405,…}}

vs everything else:

{“data”:{…},“meta”:{“action”:“change” ,“entity”:“organization”,“timestamp”:"“2023-03-31T11:07:40.691Z”,…}}

Is there any specific reason for this?
