You are receiving the timestamp in UTC you can format it for your time zone.
e.g.
[{"id":"451d767d.1de568","type":"inject","z":"bf9e1e33.030598","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"date","x":180,"y":4180,"wires":[["24f0cea0.ec617a"]]},{"id":"24f0cea0.ec617a","type":"change","z":"bf9e1e33.030598","name":"","rules":[{"t":"set","p":"payload","pt":"msg","to":"$moment($$.payload).tz(\"Europe/Berlin\").format()","tot":"jsonata"}],"action":"","property":"","from":"","to":"","reg":false,"x":320,"y":4220,"wires":[["2d2a3654.07f15a"]]},{"id":"2d2a3654.07f15a","type":"debug","z":"bf9e1e33.030598","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":500,"y":4180,"wires":[]}]
Jsonata expression
$moment($$.payload).tz("Europe/Berlin").format()
Or you can use "CET" as timezone in expression
