如何获取特定时区中特定时间段的纪元时间？

import datetime
import pytz

# 目标时区
target_timezone = pytz.timezone('Asia/Shanghai')

# 特定时间段
start_time = datetime.datetime(2022, 1, 1, 0, 0, 0)
end_time = datetime.datetime(2022, 1, 1, 23, 59, 59)

# 转换为目标时区的本地时间
start_time_local = target_timezone.localize(start_time)
end_time_local = target_timezone.localize(end_time)

# 转换为纪元时间
start_time_epoch = int(start_time_local.timestamp())
end_time_epoch = int(end_time_local.timestamp())

print("起始时间的纪元时间:", start_time_epoch)
print("结束时间的纪元时间:", end_time_epoch)
