The "Duration" column in the Profiler. In SQL 2008, it shows the timings in Microseconds (i.e. divide by a million to get seconds) and in SQL 2005, it shows the execution time in Milli Seconds. There is also a StartTime and EndTime column.

You can export the data into a table and then manipulate data using t-sql. You can either display "Duration" Column in seconds or subtract EndTime with StartTime. Hope this help. See the image attached.
