Ethereal-users: [Ethereal-users] Odd timestamp behaviour when saving filtered files

I have attached two capture files. The first (routera6.cap) was creating using snoop on a Solaris server. The second (Netflow-v9-sample2.cap) was created by loading the first file into Ethereal v0.10.13 and then saving a filtered subset of the packets. (I don't remember the exact filter I was using, but packet #1 in the smaller file is the same as packet #6 in the larger file.)
 
Now when I load the second, smaller file into Ethereal some of the delta times are negative. If I expand the Frame information,  some of the arrival times have a negative fractional part (packets #1, 2), some have negative time since first frame (packet #4), and some have negative delta from previous packet (packet #6).
 
Is this a known problem when saving filtered files?
 
Thanks,
 
Paul Sellnow
