Ruby on rails Capistrano/Mercurial/tar“；“未来的时间戳”；消息

我在使用capistrano部署rails应用程序时遇到间歇性问题。将.gz上载到服务器后，日志显示来自tar的错误，该错误表示时间戳在将来（请参阅下面的输出）。对于应用程序中的每个文件，此消息都会重复

我将服务器时间与.tar.gz文件的数字名称进行了比较，结果确实提前了几分钟。但是这与文件上的实际时间戳有什么关系呢？我如何才能正确部署我的更改

听起来你的时钟有点歪。过程中涉及的所有计算机--提交、发送、同步接收/部署？

我部署到的暂存/生产服务器与我的本地计算机位于不同的时区，但一直都是这样。Capistrano能够适应时区差异，不是吗？我确信它考虑了时区，但你仍然可以有时钟偏差。如果一个认为是东部8点01分，另一个认为是中部7点02分，你就有时钟偏移。这是我的问题。我的钟快了。它显示了未来10分钟的日期。在本地计算机上运行

date

，然后通过SSH连接到服务器并在那里运行

date

。如果比较输出并注意到较大的偏移，则可以将时钟与例如NTP同步：

$sudo ntpdate-s time.nist.gov
