It works if change the code to:

import scala.compiletime.constValueTuple
import scala.deriving.Mirror.ProductOf

case class C(date: Int, time: Int)

inline def labelsOf[A](using p: ProductOf[A]): Tuple = constValueTuple[p.MirroredElemLabels]

val labels = labelsOf[C].toList
val header = labels.map(_.toString)
