You could try the 'Last Written' <a href="https://ss64.com/nt/dir.html" rel="nofollow noreferrer">time options associated with the DIR command</a>
/T:C -- Creation Time and Date 
/T:A -- Last Access Time and Date 
/T:W -- Last Written Time and Date (default)
<pre><code>DIR /T:W myfile.txt
</code></pre>
The output from the above command will produce a variety of additional details you probably wont need, so you could incorporate two FINDSTR commands to remove blank lines, plus any references to 'Volume', 'Directory' and 'bytes':
<pre><code>DIR /T:W myfile.txt | FINDSTR /v &quot;^$&quot; | FINDSTR /v /c:&quot;Volume&quot; /c:&quot;Directory&quot; /c:&quot;bytes&quot;
</code></pre>
Attempts to incorporate the blank line target (/c:&quot;^$&quot; or &quot;^$&quot;) within a single FINDSTR command fail to remove the blank lines (or produce other errors) when the results are output to a text file.
This is a cleaner command:
<pre><code>DIR /T:W myfile.txt | FINDSTR /c:&quot;/&quot;
</code></pre>

blocks|key|1136998|text|如果你能引入一个可执行文件，我推荐(来自GNU+CoreUtils+for+Windows的)+gdate.exe。它可以提供当前日期或文件的日期，有许多不同的格式，并且是可定制的。我使用它来获取文件的最后修改日期-时间，我可以在不进行任何解析的情况下进行比较(即，独立于本地)，使用%25s+(从纪元开始的秒数)，可选地使用%25N来获得纳秒精度。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1136999|下面是一些例子：|1137000|C:\>dir+MyFile.txt

If you're able to bring in an EXE, I recommend <code>gdate.exe</code> (from <a href="http://gnuwin32.sourceforge.net/packages/coreutils.htm" rel="nofollow noreferrer">GNU CoreUtils for Windows</a>). It can give the current date or the date of a file, in many different formats, and customizable. I use it to get the last modified date-time of files that I can compare without any parsing (ie. local-independent), using the <code>%s</code> (seconds since the epoch), optionally with <code>%N</code> to get nano-second precision.
Some examples:
<pre><code>C:\&gt;dir MyFile.txt
02/10/2021 10:54 PM 4 MyFile.txt

C:\&gt;gdate -r MyFile.txt +%Y-%m-%d
2021-02-10

C:\&gt;gdate -r MyFile.txt &quot;+%Y-%m-%d %H:%M:%S&quot;
2021-02-10 22:54:50

C:\&gt;gdate -r MyFile.txt +%s
1613015690

C:\&gt;gdate -r MyFile.txt +%s.%N
1613015690.093962600
</code></pre>

I have been using the following command to get the file date. However, the <code>fileDate</code> variable has been returning blank value ever since we moved to a different server (Windows Server 2003).

<pre><code>FOR /f %%a in ('dir myfile.txt^|find /i " myfile.txt"') DO SET fileDate=%%a 
</code></pre>

Is there any other more reliable way to get the file date?

我一直在使用以下命令来获取文件日期。但是，自从我们移到另一台服务器(Windows Server2003)后，fileDate变量就一直返回空值。FOR /f %%a in ('dir myfile.txt^|find /i " myfile.txt"') DO SET fileDate=%%a 有没有其他更可靠的方法来获取文件日期？
