Diagnosis
The performance trace uses the user's local time when selecting thetrace records and displaying the trace times. To do this, it isnecessary that the user's time zone is maintained in the user masterrecord (see SU01 - Defaults), and that the time zone of the applicationserver can be determined in the kernel.
If some, or even all, of the time zone specifications are missing, itmeans that the local time cannot be determined. (The local times at ABAPlevel cannot be used, since differences between the individual timedata would sometimes occur.) In this case, the system time is used forselecting trace records.

System Response
The system sends a message and continues its work.

Procedure
Check the time zone specifications.
