I have several WDM and WDF Windows drivers that utilize WPP tracing for debugging purposes. Everything runs ok and I can capture any trace I want from any flavor of the Windows Operating System for the most part.
Recently I noticed that every ETL file that I capture from these drivers, running on Vista or newer OS, doesn’t include any timestamps. System time is reported as 0\00\ 0-00:00:00:00, Kernel time and User time fields are also blank !!!
FYI, All flavors of Windows XP and Server 2003 provide all the timestamps using the exact same driver.
I was wondering, if anybody has run into this issue before? Any advice will be appreciated. Thanks.
