+### Parameter name mismatch with actual usage in function 'Open'
+
+The implementation of the function ```client/session.go/Open()``` is mismatched with the description.
+The parameter `connectionTimeoutInMs` represents connection timeout in milliseconds.
+However, in the older version, this function did not implement correctly, regarding it as nanosecond instead.
+The bug is now fixed.
+Positive value of this parameter means connection timeout in milliseconds.
+Set 0 for no timeout.

+### Open函数参数名称与实际功能不匹配的问题
+
+函数```client/session.go/Open()```有一个参数`connectionTimeoutInMs`，表示了以毫秒为单位的连接超时时间。
+但旧版本中，该函数在实现时并未正确进行单位转换，而是将其看作了纳秒。现在该问题已修复。
+当该参数为0时，表示不设置超时时间；当设置为正数时表示以毫秒为单位的超时时间。
