The actual_flows_start equation I gave before was total junk.

Does the following look more reasonable?

unix_flow_start = (ntohl(flow->ainfo.time_sec)
	- ntohl(flow->ainfo.sys_uptime_ms)/1000)
	+ ntohl(flow->ftimes.flow_start)/1000;

This appears to give relatively sensible results, but is it correct?
