Gengliang Wang resolved SPARK-36045. ------------------------------------ Resolution: Won't Do > TO_UTC_TIMESTAMP and FROM_UTC_TIMESTAMP should return TimestampNTZ > ------------------------------------------------------------------ > > Key: SPARK-36045 > URL: https://issues.apache.org/jira/browse/SPARK-36045 > Project: Spark > Issue Type: Sub-task > Components: SQL > Affects Versions: 3.3.0 > Reporter: Gengliang Wang > Priority: Major > > Currently, the SQL function to_utc_timestamp is confusing: it just takes the > timestamp value in the local timezone and then pretends it’s in the provided > timezone and then returns the UTC value, but the result is still treated as > local timezone! > The same issue happens in from_utc_timestamp as well. > We even tried to deprecated in the OSS community: > https://github.com/apache/spark/commit/c5e83ab92c0cb514963209dc3e70ba0e24570082 > We should make TO_UTC_TIMESTAMP and FROM_UTC_TIMESTAMP return TimestampNTZ, > which makes a lot of sense. converting the current local time to/from UTC > local time. > The functions should accept both Timestamp types: > 1. given TimestampLTZ, convert it to TimestampNTZ and continue step #2 > 2. given TimestampNTZ, convert it as to/from UTC local time. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
