Resolves elastic#110008 As discussed elsewhere, this does NOT allow for truncating to a value smaller than a millisecond. Our timespan literal syntax doesn't allow specifying less than a millisecond, and the rounding infrastructure also does not support it. We also had a discussion regarding the return type, and decided that it made sense to keep the type as date_nanos, even though the truncation will always produce a millisecond-rounded (or higher) value. --------- Co-authored-by: Elastic Machine <elasticmachine@users.noreply.github.com>
