谢谢你看我的问题.真的是把我的头撞墙了。
我试图从一堆.bin文件中提取日期。这些文件是（可能）由一个用GFA Basic编写的程序创建的。我有一个标签序列的样本。
我想我已经把标题缩小到了这个序列，我想日期时间戳一定在其中（我手头没有标注的时间，但我只需要能够提取日期）。
谁能帮我从这些十六进制序列中找出日期？我似乎无法解读这里的模式。
更新：如果这确实是一个用GFA Basic写的对象，我发现以下信息出来了：（来源：GFA Basic。http:/freddo.chez.comGfaBasicGFABASIC.TXT。 )
~XBIOS(22,L:t%)
Sets date and time
t% Bits 0-4: seconds
5-19: minutes
11-15: hours
16-20: day
21-24: month
25-31: year - 1980
任何指点都将是非常棒的.再次感谢。

没有 轻松 可见的模式。如果我们把十六进制转储转换成ASCII码，我们会得到一堆乱码。
临时文件有上面的文本，这些操作将日期剥离出来，并将其传递给xxd来反转hexdump。

如果这些字节表示一个日期，有一个特殊的编码，你可能需要根据它的编程语言来确定。或者它可能是一个程序特有的自定义编码，在这种情况下，它将更难解读。
