将要到法庭出示相关证据给法官，都是些EMAIL通信，但都是中文的，如果我自己翻译
的话，可行吗？需要公证之类吗？如何公证？

88铂猫和88钯猫都留拍了。
88钯是68分，3万rmb起拍

做Project，所有的程序都在Linux下面，想调用Excel，尤其是PivotChart,有人做过吗
？

Please describe the principle and assumptions of its algorithm.
How accurate it can be?
Does it assumes the network latency is a stable constant + noise?
Thanks in advance.

88钯是章，没面值的不会太热门吧。

在Linux之下先安装Wine, 在安装Excel?
Wine:
http://en.wikipedia.org/wiki/Wine_%28software%29
Wine is a free software application that aims to allow computer programs
written for Microsoft Windows to run on Unix-like operating systems. Wine
also provides a software library, known as Winelib, against which developers
can compile Windows applications to help port them to Unix-like systems.

多谢, 不过还是希望实际研究过这个东西的朋友来说说, 到底这个基本假设在现在的互
联网上有多大程度 valid.

It looks like the basic idea is to combine multiple measurements of time
difference to calculated a theoretical offset which might be very close to
the true time.
Given that nowadays internet is way faster than when NTP was designed, I
think its accuracy is getting better. As long as you are not using a Chinese
server from NA (which is probably taken care of by the protocol) the delay
seems to be generally very small, so it's claim of ms accuracy seems to be
reasonable.
