@DanCodedThis and @alamb I looked at [snowflake documentation](https://docs.snowflake.com/en/sql-reference/functions/dateadd), [Spark documentation](https://spark.apache.org/docs/latest/api/python/reference/pyspark.sql/api/pyspark.sql.functions.date_add.html) and [postgres documentation](https://www.postgresql.org/docs/current/functions-datetime.html) - Postgres provide a generic API that's based on Intervals - Snowflake provides a simpler API where you provide the interval as a combination of timeUnit * number of units - Spark supports only days as a timeunit Implementing the Postgres approach seems the most flexible solution, and then we can implement a Snowflake dialect maybe to parse a snowflake-like UDF invocation into the Postgres-style? -- This is an automated message from the Apache Git Service.
