Coordinated Universal Time (UTC) Considerations
Plant Applications 5.x supports Coordinated Universal Time (UTC) as an option on a new installation
of the Proficy Server. When you install a new Proficy Server, you can use the time zone of the server
to store your data as you would in versions earlier than 5.0 or you can use the UTC option. The UTC
option is required to support a Regional Server where plants span time zones. It is also required to
support storage of time across the Daylight Saving Time (DST) boundary. UTC is similar to using
GMT +0:00 as your time zone, with the exception that UTC does not acknowledge Daylight Saving
Time. For example, GMT -6:00 is minus five hours from UTC, when adjusting for Daylight Saving
Time. When you choose the UTC option, all the data is stored on your server in UTC time regardless
of the time zone of the server.
Reporting and UTC
Plant Applications displays, such as Autolog, support UTC including displaying data across the DTS
boundary. When data comes into a display, the timestamp is converted to the time zone of the client.
For example, a test value with a UTC timestamp of 07:00:00 would be displayed with a timestamp of
02:00:00 on a client with a time zone of GMT -6:00 (assuming Daylight Saving Time). For data that
crosses the Fall DST boundary, you will see multiple rows/columns, depending on the display, in the
same time range. The rows/columns will be in order of UTC. For example, consider a time based
Autolog display with columns every 30 minutes. Assuming your DST boundary is at 2:00 AM, the first
1:30 AM column in Autolog will be from before 2:00 AM and the second 1:30 AM column will be from
after the DST boundary.
UTC-enabled standard reports are scheduled to be supported as part of the first SIM for this version
of Plant Applications. The SIM is expected to be out within few months of the initial release of Plant
Applications 5.0, and a UTC-enabled Excel Add-in is expected to follow soon after. For the initial
release of Plant Applications 5.0, our standard reports, including the Add-in for Excel, do not support
UTC.
NOTE: If you have custom reports, they will need to be rewritten if you wish to use UTC.
Upgrading Plant Applications to use UTC
There is no automated upgrade path to use UTC on an existing Plant Applications installation.
Therefore, we are providing the following manual options for you to consider, if you decide to upgrade
to using UTC on an existing database. We are unable to go through all the scenarios or provide the
technical details of how to implement them; these are just options to consider. With both options you
must first make a copy of your production database.
IMPORTANT: Before proceeding, it is important to understand that these options require
advanced knowledge of both SQL Server and Plant Applications.
