Oracle Database 12c - DataPump (LOGTIME Parameter)

The LOGTIME parameter determines if timestamps should be included in the output messages from the expdp and impdp utilities.

LOGTIME=[NONE | STATUS | LOGFILE | ALL] 
The allowable values are explained below.

1. NONE : The default value, which indicates that no timestamps should be included in the output, 
   making the output look similar to that of previous versions.
2. STATUS : Timestamps are included in output to the console, but not in the associated log file.
3. LOGFILE : Timestamps are included in output to the log file, but not in the associated console messages.
4. ALL : Timestamps are included in output to the log file and console.
