Delta save timestamp as timestamp with time zone

[BorislavBlagoev]

Hello! I have the following problem. I want to save the delta table and that table contains timestamp columns, but when I try to write that table with spark the timestamp columns become timestamp with the time zone. This is a problem in my case because when I try to read the table from Trino the columns are in timestamp with time zone format. Does anyone know how I can change this behavior?

in Spark sql "Spark SQL defines the timestamp type as

TIMESTAMP WITH SESSION TIME ZONE"

you can check your timezone settings. Sometimes in such a case can be more comfortable to store timestamp as Long.

Here is more info about timezones https://docs.databricks.com/spark/latest/dataframes-datasets/dates-timestamps.html

If you share example file and code I could help more.

@Hubert Dudek​ This is happening if I use Delta. If I use parquet spark save the column in timestamp without time zone.
