Configure time zone options

You can configure a trend so that data appears with time stamps that reflect any time zone. For example, you may want to configure the trend to the same time as the location of the server.

To configure time zone options:

1. On the Historian tab, in the Publish group, click Options, and then click Options. The Options dialog box appears.

2. Select the Time Zone tab. The grid displays the current time zone and daylight saving time settings for the following entities:

   Entity	Description
   Application	The Historian Client Workbook application. You can select the time zone for the data as it appears in the Workbook application.
   Client	The physical computer on which the Workbook application is installed. The time zone displayed for the client is for informational purposes only and cannot be changed using the Workbook application.
   <Server>	The Historian(s) to which the Workbook application is currently connected. The time zone displayed for the server(s) is for informational purposes only and cannot be changed using the Workbook application.

3. In the Time zone list, click the name of the time zone to use for the Workbook application.

   The time zone for the Workbook application in the grid displays the new time zone picked.

   For example, consider a SCADA application that monitors a pipeline between Houston, Texas and Lake Forest, California. The Workbook application is installed on a computer located in Houston, Texas. Therefore, the time zone entry for the Client entity displays Central Standard Time. The server is also located in Houston, Texas. The time zone entry for the Server entity also displays Central Standard Time. You want to send a Workbook file to an engineer located at the start of the pipeline in Lake Forest to aid in troubleshooting a problem. You can set the time zone of the Workbook application to reflect the time of Lake Forest, California (Pacific Standard Time), so that the workbook that you send to the engineer displays data in a time zone that is relevant to him/her.
