获取当前时间戳并设置时分秒为零点零分零秒

import java.time.LocalDate; import java.time.LocalDateTime; import java.time.LocalTime;

public class Main { public static void main(String[] args) { // 获取当前日期 LocalDate currentDate = LocalDate.now();

    // 设置时分秒为零点零分零秒
    LocalTime zeroTime = LocalTime.of(0, 0, 0);
    
    // 将当前日期和零时分秒组合得到当前时间戳
    LocalDateTime currentDateTime = LocalDateTime.of(currentDate, zeroTime);
    long timestamp = currentDateTime.toInstant(java.time.ZoneOffset.ofTotalSeconds(0)).toEpochMilli();
    
    System.out.println("当前时间戳：" + timestamp);
}
