Retention policy error

[rts-gordon]

Hi there,
There are some 'retention policy' errors. Can someone tell me what is wrong? Especially the third/forth step?

Thank you very much.

Steps to reproduce:
List the minimal actions needed to reproduce the behavior.
1, setup InfluxDB version 2.7.1 on cloud VM;
2, setup a Java Spring program with Influxdb-client-java version 6.9.0;
3, setup the Bucket retention policy to 7 days;
4, the _time of Point is three hours ahead of UTC;
5, run this program for at last a week, there are some 'retention policy' errors.

Client Version:
Influxdb-client-java 6.9.0
InfluxDB Version: 2.7.1
JDK Version: JDK 8
Platform: Linux

Expected behavior:
There are no 'retention policy' errors.
