kotlin中两个日期之间的时间

import java.time.LocalDate
import java.time.temporal.ChronoUnit

fun main() {
    val startDate = LocalDate.of(2022, 1, 1)
    val endDate = LocalDate.of(2022, 1, 10)

    val days = ChronoUnit.DAYS.between(startDate, endDate)
    val hours = ChronoUnit.HOURS.between(startDate.atStartOfDay(), endDate.atStartOfDay())
    val minutes = ChronoUnit.MINUTES.between(startDate.atStartOfDay(), endDate.atStartOfDay())
    val seconds = ChronoUnit.SECONDS.between(startDate.atStartOfDay(), endDate.atStartOfDay())

    println("Days: $days")
    println("Hours: $hours")
    println("Minutes: $minutes")
    println("Seconds: $seconds")
}

Days: 9
Hours: 216
Minutes: 12960
Seconds: 777600
