What is the unit of the Duration column in SQL Profiler? I thought it was milliseconds but in the following Profiler row I found it contradicting with start and end time:
spid=163
duration=11310646
starttime=2010-04-06 17:45:24.480
endtime=2010-04-06 17:45:35.790
reads=152
writes=2
cpu=16
eventclass=12
textdata= DELETE FROM dbo.[Icon] WHERE Id = 20087
FYI, I am using SQL Server 2008.

I found the answer here. It says
In SQL Server 2005 and later, the SQL Server Profiler graphical user interface displays the Duration column in milliseconds by default, but when a trace is saved to either a file or a database table, the Duration column value is written in microseconds
I was watching them after saving the trace file in database.
