I want to change the ELB access log from UTC to JST.

Currently, I am using a mechanism to save access logs from ELB to s3.
We are currently collecting logs from ELB, but the standard output is UTC.
The official document only says that it will be printed in ISO 8601 format.
There were no details.

So I have a question like JST(UTC+9)
Do you have any settings to output?

If not, I am thinking of adding logic to change to JST in the program.
Thank you for your cooperation.
