How to timestamp request logs with millisecond accuracy in Apache 2.0
提问by Ben Williams
How do I configure Apache 2.0's log format so that it timestamps each request log with millisecond (or microsecond) accuracy? The docssay that timestamps are specified in strftime format and strftime doesn't seem to handle anyting smaller than seconds.
如何配置 Apache 2.0 的日志格式，以便它以毫秒（或微秒）精度为每个请求日志添加时间戳？该文件说，时间戳中的strftime格式和strftime规定似乎并没有处理点儿小于秒的。

I don't think it's possible (without rewriting APR, atleast). Apache uses apr_strftime. On Unix, this calls the C library's strftime, but doesn't even fill milliseconds into struct tm (not surprisingly, because this structure doesn't usually support milliseconds in the first place). The Windows versions isn't much different.
我认为这是不可能的（至少不重写 APR）。Apache 使用apr_strftime。在 Unix 上，这会调用 C 库的 strftime，但甚至不会将毫秒填充到 struct tm 中（这并不奇怪，因为该结构通常首先不支持毫秒）。Windows 版本没有太大不同。

use %D option for microsecond accuracy
使用 %D 选项以获得微秒精度
