  override fun canDecorate(position: Int): Boolean = periods.getOrNull(position) is Program

  override fun getStartUnixMillis(position: Int): Long = periods.getOrNull(position)?.startAt ?: 0

  override fun formatUnixMillis(unixMillis: Long): String =
    LocalDateTime.ofEpochSecond(unixMillis / 1000, 0, ZoneOffset.UTC).format(formatter)
}

class StageNameDecoration(private val periods: List<Period>, ...) : ColumnNameDecoration(...) {

  override fun getColumnNumber(position: Int): Int {
    return periods.getOrNull(position)?.stageNumber ?: 0
