Description

I provision a service with "timezone": "Asia/Tokyo" using MQTT binding.
The sensor push several attributes/measruements. The issue is the timezone for observedAt is always UTC and ignoring any timezone provided by service or device.

Docker image date time: Thu Dec 14 11:53:07 UTC 2023
IoT Agent log -> "observedAt": "2023-12-14T11:53:07.152Z**"
Orion-LD -> "observedAt": "2023-12-14T11:53:07.152Z"
What i expected Orion-LD -> "observedAt": "2023-12-14T20:53:07.152Z"

Maybe the bug is here

Research direction

Start in lib/services/ngsi/entities-NGSI-LD.js at the linked line and trace how observedAt is generated for multivariable sensors. Compare the configured service or device timezone with the emitted NGSI-LD timestamp, then verify the behavior with the relevant test suite. Done means observedAt honors the configured timezone instead of always using UTC.
