我已经寻找了很长时间，试图找到一种方法，让 PDF（使用 XeTeX 创建）根据打印日期（而不是编译日期）相应地调整日期。我熟悉\date、、&包等，但这些都不是我想要的。我还在 tex.stackexchange.com 上找到了一个页面，但我大多不理解（\datedatedatenumberdatetime文件创建日期) 这越来越接近我想要的，但并不完全是。哦，顺便说一句，如果它是独立于平台的，那就太好了，因为不是所有的员工都有同一台电脑。
这里的想法是为员工创建时间表，他们可以在工作前打印出来并自动为他们创建日期。这是时间表的粗略（真正）草稿（大多数评论都是我使用涉及pgf/tikz包的一些对我来说很新的技术 - 无关紧要）：
非常感谢，希望一切清楚！

答案1
答案2
在编译时将编译或其他日期放入文档中很容易。这只是另一个文本。但是，PDF 查看器无法更改此文本以进行打印！所以这两件事完全不同。
我看到的唯一方法是将一些 PDF 表单字段添加到文档中，该字段在打印 PDF 时（即打印之前）使用嵌入的 JavaScript 进行更新。您应该研究这个方向。例如，据我所知，该movie15包将 JavaScript 放入 PDF 中（但这并不是您需要的）。
你可能最终需要自己编写 JavaScript 代码。例如，你可以询问http://stackoverflow.com如何使用 PDF 打印日期更新 PDF 文本字段。
答案3
通过编译为 PostScriptdvips而不是 PDF 可以让您更好地从打印文档时直接获取当前日期 - 请参阅此常见问题解答。与 PDF 文档不同，PostScript 文档实际上是打印机执行的程序，因此每次打印时可能会生成略有不同的页面。
但是，并非所有 PostScript 版本都支持此功能，因此此功能的可用性取决于所使用的打印机。我还对从打印机读取的日期和时间的准确性有些怀疑。总而言之，这似乎不是适合您用例的可行解决方案。
答案4
如果你在 pdf 上有一个使用 JavaScript 计时的时钟，那么每次打印时，纸张上都会打印出时间，对吗？这让我想起了我们在 latex-beamer 上进行的讨论很久以前，人们就讨论过在演示中放置滴答作响的时钟。发布解决方案和现在似乎已失效的链接，但有些代码在线程中被交换（来自powerdot包）可能会有所帮助。
