Zigbee and time of day question.

[paulz-gh]

Hi,
Last week I have received a Tuya rain sensor https://www.zigbee2mqtt.io/devices/RB-SRAIN01.html#tuya-rb-srain01
And it seems to regard the moist Dutch night are as rain ;-)
But there is one other thing that surprises me. One of the measurements is Illuminance maximum for the last 24 hours.
I noticed the value resets almost exactly at midnight local time ( 2200 UTC)

How can the sensor know the local time ? There is no way to set it.
Is it part of the zigbee packets ?

Just curious,
Paul

Yes, a device can request the time over Zigbee
