Let me describe the issue that I have. There is a file which contains data from both tuners and TunerA sample rate is 42 MS/s and TunerB is 13.3 MS/s. The app dumps the processed packets number and encountered metadata (WbtVRTFileReadIterator::getCurrentMetadataAsJSON) to debug output. I start processing TunerA data. The first metadata has "GPS Fix UTC Seconds" value of 1446218004. By the time app processed 815M samples (which should constitute approx. 19 seconds of data) the metadata timestamp is 1446218019 - only 15 seconds later than the starting value. The difference is even bigger in case of TunerB. After processing 250M samples (~18 sec.) the metadata timestamp is 1446218009 - moved forward by only 5 sec. What is happening here and is it the expected behavior?
