Julian Hyde commented on CALCITE-5450:
--------------------------------------
I don't think you need to change Avatica. You can accomplish everything using
the custom time frames I added to Calcite in CALCITE-5155. In particular use
{{TimeFrameSet.Builder.withEpoch}} to set the start day of a week time frame (I
thought it was called {{withOffset}} and didn't have time to start my IDE to
check).
> Add to parser WEEK(WEEKDAY) for custom time frames

> Issue Type: Improvement
> Reporter: Oliver Lee
> Priority: Minor
>
> Some BIG_QUERY functions (i.e. {{{}EXTRACT(){}}}, {{DATE_TRUNC()}} ) can
