为 Webkit (Google Chrome) 时间戳保留多少位？
我知道 Google Chrome 使用整数时间戳，正确地称为 Webkit 时间戳，它是根据自 01/01/1601 00:00:00 UTC 以来的微秒数计算的。我不确定这是一个 64 位有符号整数（这最有意义）还是 56 位整数？
下面是一个时间戳示例：12883423549317375。这会解码为 Sun, 05 April 2009 16:45:49 UTC。关于其工作原理有什么好的参考吗？我搜索了Webkit网站，没有找到这个时间戳的文档。
I know that Google Chrome uses an integer timestamp, properly called the Webkit timestamp, that is calculated by the number of microseconds since 01/01/1601 00:00:00 UTC. What I'm not sure is whether this is a 64-bit signed integer (which would make the most sense) or a 56-bit integer?
Here's an example timestamp: 12883423549317375. This decodes as Sun, 05 April 2009 16:45:49 UTC. Any good reference out there for how this works? I searched the Webkit website and found no documentation of this timestamp.

Chromium 中的时间通常为 内部表示为
int64。查看base::Time和各种特定于平台的实现，了解有关如何进行转换的详细信息。Time in Chromium is generally represented internally as an
int64. Take a look atbase::Timeand the various platform-specific implementations for details about how the conversions take place.此外，由于这些时间戳经常在 SQLite 数据库（在 Chrome 数据中）中找到，我经常必须找到一种即时解码它们的方法。我最常访问的书签之一位于 http: //linuxsleuthing.blogspot.co.uk/2011/06/decoding-google-chrome-timestamps-in.html 告诉您如何在 SQL 中执行此操作 询问。
其中 time 是存储 webkit 时间戳的列的名称。
In addition, as these timestamps are often found in SQLite databases (in Chrome data) I often have to find a way to decode them on-the-fly. One of my most-visited bookmarks is at http://linuxsleuthing.blogspot.co.uk/2011/06/decoding-google-chrome-timestamps-in.html which tells you how to do this as part of an SQL query.
Where time is the name of the column the webkit timestamp is stored in.
