Vitalii Diravka commented on DRILL-4116:
----------------------------------------
[~rkins]
[Configure the default time zone format in /conf/drill-env.sh by adding
-Duser.timezone=UTC to
DRILL_JAVA_OPTS|https://drill.apache.org/docs/data-type-conversion/#time-zone-limitation]
Your timezone possibly is overridden in the /conf/drill-env.sh file or directly
in system linux env DRILL_JAVA_OPTS property.
The question is should datediff() function return different results for
different timezones? If yes the description of the jira should be edited, if
not - jira can be closed.
> Inconsistent results with datetime functions on different machines
