-----------------------------------
Assignee: Maxim Gekk
> Overflow/round errors in conversions of milliseconds to/from microseconds
> -------------------------------------------------------------------------
>
> Key: SPARK-30925
> URL: https://issues.apache.org/jira/browse/SPARK-30925
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Maxim Gekk
> Assignee: Maxim Gekk
> Priority: Major
>
> Spark has special methods in DataTimeUtils for converting microseconds
> from/to milliseconds - `fromMillis` and `toMillis()`. The methods handle
> arithmetic overflow and round negative values. The ticket aims to review all
> places in Spark SQL where microseconds are converted from/to milliseconds,
> and replace them by util methods from DateTimeUtils.
