In the files I captured with NetProb32 demo-version and the sample "Nw_test.trc"-file that was included with the
NetProb (v1.34) and NetProb32 (v1.3) demo versions, there was no absolute time reference at all - only relative timestamps since the capturing was started ("Elapsed time").
However I don't know if maybe your capture looks different from this.

Below is a sample file I captured with NetProb32 demoversion, and my guess of what some of the data means

64 00 NetProb file-format (It seems that several of the binary files generated by NetProb starts with 64 00)
01 00 TRC-format (0100 = means TRC capture it seems,
0400 = seems to mean PKT packet generation file - with another file format than this,
0700 = CFG configuration file - with another file format than this)
05 00 Number of packets stored (I think) = 5
(only 5 will be visible since captured with demo version but there are really a few more packets in the file.
The demo file that was included had value "06 00" and there was 6 packets that I could view)
