--------------------------------
Work in progress.
> Add the time_trunc() function
> -----------------------------
>
> Key: SPARK-51554
> URL: https://issues.apache.org/jira/browse/SPARK-51554
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 4.1.0
> Reporter: Max Gekk
> Priority: Major
>
> The time_trunc() function returns time truncated to the unit specified in
> unit.
> h4. Syntax
> {code:sql}
> time_trunc(unit, expr)
> {code}
> h4. Arguments
> * unit: A STRING literal.
> * expr: A TIME, or STRING with a valid time format.
> h4.
> A TIME\(n\) with n matching that of expr.
> h4. Notes
> Valid units for unit are (case-insensitive):
> * 'HOUR': zero out the minute and second with fraction part
> * 'MINUTE': zero out the second with fraction part
> * 'SECOND': zero out the second fraction part
> * 'MILLISECOND': zero out the microseconds
> * 'MICROSECOND': everything remains
> If the unit is not well-formed the function returns NULL.
> h4. Examples
> {code:sql}
> > SELECT time_trunc('HOUR', '09:32:05.359');
> 09:00:00
> > SELECT time_trunc('MILLISECOND', '09:32:05.123456');
> 09:32:05.123
> -- Not a recognised unit
> > SELECT time_trunc('MS', '09:32:05.123456');
> NULL
> {code}
