Venki Korukanti commented on CALCITE-1177:
------------------------------------------
Hi [~julianhyde], Rebased the patch to just after the last release of Calcite.
[Here|https://github.com/vkorukanti/calcite/commits/CALCITE-1177] are the new
changes. While writing the tests for
{{SqlOperatorBaseTest.testFloorFuncInterval}}, I realized convertlet for
functions extract, floor and ceil is out of sync with the supported time units.
Some of the newly supported units may not rewritten in div and multiplication
(ex. millennium depends on type of calendar). Should we leave the convertlet
table as it is or implement for certain calendar (eg. ISO)?
> Add support for more time units in extract function
