If you or your Organization or Project Administrator set your timezone to something other than the default for your project location, you’ll see a different date displaying in the Event Log, transmittal view and Transmittal History than on the same Transmittal in the Tasks page and Search results.
Each Aconex project is housed on a certain instance, which typically relates to the project location. To provide a single source of truth for your project, all dates are recorded in UTC (Coordinated Universal Time) on that instance.
If you select a timezone other than the default, dates on individual transmittals will reflect the local time in that timezone in the Event Log, transmittal view and Transmittal History. However, the search results and Tasks list will still show dates in UTC on your instance, so you’ll know what the “universal” date of document activity was for all project participants.
