Jesus Camacho Rodriguez updated HIVE-22241:
-------------------------------------------
Description:
UDF that converts a date/timestamp to new *proleptic Gregorian calendar* (ISO
8601 standard), which is produced by extending the Gregorian calendar backward
to dates preceding its official introduction in 1582, assuming that its
internal days/milliseconds since epoch is calculated using legacy
*Gregorian-Julian hybrid* calendar, i.e., calendar that supports both the
Julian and Gregorian calendar systems with the support of a single
discontinuity, which corresponds by default to the Gregorian date when the
Gregorian calendar was instituted.
