 * - `'minutes'`: seconds and milliseconds are set to 0.
 * - `'seconds'`: seconds are preserved and milliseconds are set to 0.
 * - `'exact'`: the original value is preserved unchanged.
 * @param values - array of values provided to the query operator; each top-level Date or date-like string will be transformed
 * @param timePrecision - controls how precisely time information is preserved: `'minutes'`, `'seconds'`, or `'exact'`
