在Python 中通过 time.time() 函数获取纪元秒数,它可以把从 epoch 开始之后的秒数以浮点数格式返回。 import time print(time.time()) # 输出结果 1615257195.558105 时间戳大量用于计算时间相关程序,属于必须掌握内容。 1.3 获取可读时间 时间戳主要用于时间上的方便计算,对于人们阅读是比较难理解的,如果希望获取可...
对于Unix,epoch(纪元)是1970年1月1日00:00:00(UTC)。要找出给定平台上的epoch,请使用time.gmtime(0)进行查看,例如橡皮擦电脑显示: 代码语言:txt AI代码解释 time.struct_time(tm_year=1970, tm_mon=1, tm_mday=1, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=3, tm_yday=1, tm_isdst=0) 术...

我们的下一个支持函数是parse_windows_filetime(),改编自第七章中的先前日期解析配方,基于日志的证据配方。我们借用这个逻辑并将代码压缩为只解释整数并返回给调用函数的格式化日期。像我们刚刚讨论的这两个通用函数一样,它们在你的工具库中是很方便的,因为你永远不知道什么时候会需要这个逻辑。 defparse_windows_file...

import timeseconds = time.time()print("Seconds since epoch =", seconds) 1. 输出: AI检测代码解析 Seconds since epoch = 1592456227.1542935 1. time.ctime() 我们再来看看time.ctime()方法。,当中的字母c代表current,代表当前时间点。我们用代码举个实例演示一下: ...

当前时间就是相对于epoch time的秒数,称为timestamp。 1. 2. timestamp = 0 = 1970-1-1 00:00:00 UTC+0:00 1. >>> dt.timestamp() 1523507040.0 1. 2. 4.timestamp时间戳转datetime >>> datetime.datetime.fromtimestamp(st) datetime.datetime(2018, 4, 12, 12, 24) 1. 2. 5.str转...
