How to replay nanoseconds PCAP file

[Sagume Kishin]

I started with a regular microsecond PCAP file whose magic number in file header is  0xA1B2C3D4, I make it a nanosecond file by changing the magic number to 0xA1B23C4D and for every packet record I multiply its second time stamp by 1000.

I can easily replay the microsecond one by using push --port 1 -r -f 190_packet.pcap -c 1 in trex-console, but pushing 190_packet-ns.pcap does not produce any traffic. 

The files can be found in https://github.com/zyddnys/pcap-test/

Does TRex support nanosecond pcap file replay? or my method for creating nanosecond pcap file is wrong?

Thank you so much!
