Zigbee2Mqtt is one hour behind

Hello,
The timestamps of messages from the sensors are one hour behind the PC time and Gladys time:

docker logs gladys-z2m-zigbee2mqtt:
Zigbee2MQTT:info 2022-02-15 13:11:51: MQTT publish: topic ‹ zigbee2mqtt/Contact ›, payload ‹ {« battery »:100,« contact »:true,« linkquality »:182,« voltage »:3005} ›

System time: Tue 15 Feb 14:13:11 CET 2022

docker logs gladys:
Gladys time: 2022-02-15T14:15:00+0100 handleMqttMessage.js:100 () Zigbee2mqtt device Contact, feature linkquality not configured in Gladys.

How to configure the timezone for Zigbee2Mqtt? Which parameter?

Thank you for your help.
