> 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.
