Hi ,

I am using Softflowd IPFIX supported version ( Revision : 80aac3b2fec3
) downloaded from google code. I export flows in IPFIX format to
collector server ( NFDUMP 1.6.10 ) . I am seeing  issue  with date and
time field when I am reading nfdump logs .

Whereas In case of Netflow v5 and v9 it is working fine means proper
date and time comes in nfdump logs.

Command run :

softflowd  -i eth3 -n 192.168.50.2:9995 -v 10 -d -t maxlife=30  -D -A milli

nfdump log :

$ nfdump -r nfcapd.201408280909

I also used sec with –A option but in that case also same problem
persist.  I attached tcpdump pcap file also. Pls find attachment.

Can anybody know why it’s happening ?
