Logstash daily indices write to wrong (yesterday) date

I implement logstash elasticsearch output to create daily indices. The index name has this format:

"default-%{[kubernetes][pod][name]}-%{+YYYY.MM.dd}"

It works perfectly, it creates index, lets say for example for pod myapp, default-myapp-2020-10-07. The problem is, I implement elasticsearch ILM, that makes older indices readonly. It is worked, when I check index setings, It has index.blocks.write: ture. But in my logs of elasticsearch, I can see errors like this:

Section blocked by: [FORBIDDEN/8/index write (api)];" is because the index is readonly.

What is interesting here, that today date should be 2020-10-07 as you see from logs timestamps, but logstash is trying write to index with date 2020.10.06. I do not understand why. This is happening for more indices.

I am using ELK Stack 7.8.1.
