Pre-Oracle9i, the times recorded by Oracle only have a resolution of 1/100th of a second (10mS). As of Oracle9i some times are available to microsecond accuracy (1/1,000,000th of a second). The timestamp can be used to determine times between points in the trace file. The value is the value in v$timer when the line was written. If there are TIMESTAMPS in the file you can use the difference between ‘tim‘ values to determine an absolute time. hv Hash id. ad SQLTEXT address (see v$sqlarea and v$sqltext).
