Please see internal error for more details about the possible cause of this runtime error and how it could be avoided.
The ABAP interpreter always determines the local time relative to time
on the database. To do this, it obtains the time of the application
server and the time of the database at regular intervals. The times
must both meet certain plausibility criteria. The time of the second
time stamp obtained cannot be earlier than that of the first time stamp
obtained.
In the present case, the plausibility criteria for the local time on
the application server have been violated.
Older time stamp: <runtime parameter>
More recent time stamp: <runtime parameter>
