[Bug] Convert timestamp_ltz field contents using local time zone

• [X] I searched in the issues and found nothing similar.

Paimon version

0.8

Compute Engine

flink

Minimal reproduce step

1. Create a mysql table containing the timestamp type, and specify the time zone for mysql server to be UTC+8
2. Use flink-cdc to import the data of the table into kafka
3. Create a paimon table, which uses a timestamp_ltz type field to store the value of the timestamp type field in mysql
4. If you query the paimon table in UTC+8, you will find that there are still 8 hours missing

What doesn't meet your expectations?

The content of the timestamp_ltz field retrieved from the Paimon table should be the same as in mysql

Anything else?

I think the root cause is that we use the utc time zone to read the data from kafka, but use the current time zone to write the data to paimon.
