如何在一小时之内启动AlarmManager？

AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + 5000, pendingIntent);

import datetime
import logging
from qcloud_cos import CosConfig
from qcloud_cos import CosS3Client
from qcloud_cos import CosConfig
import time

logger = logging.getLogger()
logger.setLevel(logging.INFO)

cos_config = CosConfig()
cos_config.set_region("ap-guangzhou")

s3_client = CosS3Client(cos_config)

def set_alarm(alarm_time):
    """
    设置警报时间
    :param alarm_time: 时间戳或字符串，格式为 "YYYY-MM-DD HH:MM:SS"
    """
    now = datetime.datetime.now()
    if alarm_time.endswith("00:00:00"):
        # 如果时间为00:00:00，直接返回
        return

    # 如果时间不为00:00:00，计算下一个00:00:00时间并等待
    next_alarm_time = now + datetime.timedelta(minutes=1)
    while next_alarm_time.strftime("%Y-%m-%d %H:%M:%S") != alarm_time:
        next_alarm_time += datetime.timedelta(minutes=1)

    logger.info("Alarm set for: %s" % next_alarm_time.strftime("%Y-%m-%d %H:%M:%S"))

    # 触发警报
    try:
        alarm_manager = AlarmManager.shared()
        alarm_manager.set_alarm(next_alarm_time)

    time.sleep(int(next_alarm_time.strftime("%M")) * 60)

set_alarm("2023-05-27 12:00:00")
