Tech Note 850 - Historian Hyper-V Guest Image and Time Synchronization

April 17, 2012

When using Wonderware Historian Server as a guest within Hyper-V hosts, you may encounter the following message in the ArchestrA Logger:

"Server time is shifting (Expected time, Current time)" (02/06/12,11:24:48,766, 02/06/12,11:24:45,453) [...; Config.cpp; 2040]

Sometimes the time synchronization may shift 5 or 6 seconds ahead. However, this is not a Wonderware product issue, but rather an issue related to Hyper-V hosts. Normally this is resolved simply by installing Integration Services for the Hyper-V guest image, but there are cases where the Integration Services may actually cause this problem. Here is a workaround solution for customers facing this issue.
