Nothing, seems like a DST bug in SmartPSS. The thread below refers to the Mac version of SmartPSS, but IIRC, the Windows version does the same thing.
MacOS SmartPSS 2.0 exporting clips via the scissor tool off by one hour
The workaround I first started to use was to write down the proper begin/end times, then go back and clip one hour earlier. So in your case, export 11:10 to 11:13.
Lately it's been easier for me (on my Mac) to do a QuickTime screen capture of the SmartPSS playback window.
