时间相减 示例kotlin LocalDateTime

    fun test1(){val d1: LocalDateTime = LocalDateTime.parse("2023-05-06 00:00:00", DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"))val d2: LocalDateTime = LocalDateTime.parse("2023-05-07 15:12:00", DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"))val d3: LocalDate = LocalDate.parse("2023-05-06 00:00:00", DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"))val d4: LocalDate = LocalDate.parse("2023-05-07 15:12:00", DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"))val diff: Duration = Duration.between(d1, d2)val period: Period = Period.between(d3, d4)val diffDays: Long = diff.toDays()val years: Int = Math.abs(period.getYears())val months: Int = Math.abs(period.getMonths())val days: Int = Math.abs(period.getDays())println("Diffrence between dates is : " + diffDays + "days")println("Diffrence is : $years year, $months months, $days days")println(d1.month.value)}

结果

Diffrence between dates is : 1days
Diffrence is : 0 year, 0 months, 1 days
