Arithmetic overflow error converting numeric to data type numeric

Apr 27, 2011 at 3:30 PM

When I try to update a device in the openPDC Manager I get the following error:

"Arithmetic overflow error converting numeric to data type numeric."

Then, when I change my regional settings to English (United States) I am able to update the device.

But I get the following message in the openPDCConsole:

[SEL-751A] Defaulting to UTC. Failed to find system time zone for ID "Hora oficial do Brasil": The time zone ID 'Hora oficial do Brasil' was not found on the local computer.

We haven't done much testing on non-English platforms, however, we try to fix these kinds of issues as they are reported, so I'll copy this to a work item.

Perhaps at some point we can recruit some volunteers to help provide some system level translations for the product...

Hi Ritchie,

Regarding the TimeZone error, I think I have a solution.

I think this issue could be fixed with the following change: instead of using the StandardTime to create the dictionary, it should use the ID.



public static Dictionary<string, string> GetTimeZones(bool isOptional)
   Dictionary<string, string> timeZonesList = new Dictionary<string, string>();
   if (isOptional)
      timeZonesList.Add("", "Select Timezone");

   foreach (TimeZoneInfo tzi in TimeZoneInfo.GetSystemTimeZones())
      if (!timeZonesList.ContainsKey(tzi.StandardName))
         timeZonesList.Add(tzi.Id, tzi.DisplayName);
         //timeZonesList.Add(tzi.StandardName, tzi.DisplayName);

   return timeZonesList;


The error occurs because int the TVA.PhasorProtocols.PhasorMeasurementMapper.Initialize() the StandardTime (that was being stored in the database) is used to retrieve the TimeZoneInfo by FindSystemTimeZoneById:


if (settings.TryGetValue("timeZone", out setting) && !string.IsNullOrWhiteSpace(setting) && string.Compare(setting.Trim(), "UTC", true) != 0 && string.Compare(setting.Trim(), "Coordinated Universal Time", true) != 0)
      m_timezone = TimeZoneInfo.FindSystemTimeZoneById(setting);
   catch (Exception ex)
      OnProcessException(new InvalidOperationException(string.Format("Defaulting to UTC. Failed to find system time zone for ID \"{0}\": {1}", setting, ex.Message), ex));
      m_timezone = TimeZoneInfo.Utc;


And depending on the display language of Windows, the StandardTime and ID could be different. Causing the error.
