> Use Proleptic Gregorian calendar
> --------------------------------
>
> Key: SPARK-26651
> URL: https://issues.apache.org/jira/browse/SPARK-26651
> Project: Spark
> Issue Type: Umbrella
> Components: SQL
> Affects Versions: 2.4.0
> Reporter: Maxim Gekk
> Assignee: Apache Spark
> Priority: Major
>
> Spark 2.4 and previous versions use a hybrid calendar - Julian + Gregorian in date/timestamp
parsing, functions and expressions. The ticket aims to switch Spark on Proleptic Gregorian
calendar, and use java.time classes introduced in Java 8 for timestamp/date manipulations.
One of the purpose of switching on Proleptic Gregorian calendar is to conform to SQL standard
which supposes such calendar.
