在 Bash/Python 中转换 CIM_DATETIME [英] Convert CIM_DATETIME in Bash/Python

问题描述

我有一个从 wmic os get lastbootuptime 获取的 CIM_DATETIME 时间:

I have a CIM_DATETIME time acquired from wmic os get lastbootuptime:

20190309221835.234400-480

CIM_DATETIME 的格式如下:

yyyymmddHHMMSS.mmmmmmsUUU

如何在 Bash 或 Python 中将其转换为更人性化的内容?

How can I convert that to something more human-friendly in Bash or Python?

最理想的格式是:

Sunday, March 10th, 2019 @ 16:01:30 UTC

那或者我是否可以将其转换为诸如 Unix 时间戳之类的正常内容.如果您想知道我对非 Windows 语言的需求(Batch 中已经有很多解决方案)是因为我进行计算机取证，但我将 Linux 作为我的主要操作系统运行，所以我希望能够轻松解释我从中获得的日期WMI 变成我可以轻松解释的东西.它太小众了，我什至无法在网上找到一个工具来做到这一点.:/

That or if I could convert it to something normal like a Unix timestamp. If you're wondering my need for this in non-Windows languages (there are already many solutions in Batch) is because I do computer forensics but I run Linux as my main OS so I want to be able to easily interpret dates I get from WMI into something I can interpret easily. It's so niche I'm unable to even find a tool online to do it. :/

谢谢.

推荐答案

这是我在 Bash 中提出的解决方案.输出似乎是正确的，并且与几天前我启动 Windows 框的时间一致——就在午夜之前.我还删除了@"，因为它几乎没有让时间更好看并制作它，因此由于 date 命令，我不得不使用 CIM_DATETIME 在以下脚本中删除它无法解析.

Here is the solution in Bash i came up with. The output seems to be correct and align with the time a couple of days ago I booted up the Windows box -- just before midnight. I also removed the "@" because it barely made the time nicer to look at and made it so I had to remove it in following scripts using CIM_DATETIME due to the date command not being able to parse that.

CIM_DATETIME="20190309221835.234400-480"

date="${CIM_DATETIME:0:8}"
date="$(date -d "$date" '+%A, %B%e, %Y')"

time="${CIM_DATETIME:8:6}"
time="$(echo "$time" | sed 's/../&:/g;s/:$//')" # Adds : between hours, minutes and seconds of time so it can be parsed correctly

timezone="${CIM_DATETIME:21}"
time="$time $timezone"

time="$(date -d "$time" '+%r %Z')"

echo "$date $time"

示例输出:美国东部时间 2019 年 3 月 9 日星期六晚上 11:38:35

感谢您提供的所有解决方案.
