> In general, I would be a big fan of trying if possible of having datafusion normlize all data on input to UTC prior to processing but I worry this might not be a good idea for performance reasons. Postgrseql deal with this in the similar way <https://www.postgresql.org/docs/current/datatype-datetime.html#DATATYPE-TIMEZONES> > All timezone-aware dates and times are stored internally in UTC. They are converted to local time in the zone specified by the [TimeZone](https://www.postgresql.org/docs/current/runtime-config-client.html#GUC-TIMEZONE) configuration parameter before being displayed to the client. If that's the case, should it be `Timestamp(Nanosecond, "UTC")` or `Timestamp(Nanosecond, None)`? -- This is an automated message from the Apache Git Service.
