Time Zone Error
The time zone string reported by your computer (Tokyo Standard Time) is invalid. The results are displayed for the local time zone of the Coveo Master server (Eastern Standard Time).
On the Coveo Front-End server, the time zone from which the end-user is accessing the search interface may not be defined in the Windows registry.
On the end-user computer, the time-zone value can be missing, in an incompatible format, or corrupted.
A network device or process such as a proxy between the client and the server can intercept and modify the query received by the Coveo server.
On the Coveo Front-End server, fix the time zone registry keys (see Missing time zones - Microsoft Community).
On the end-user computer, verify the time zone in the operating system parameters.
