Hi all.

In fields FIRST and LAST in a stream should be system uptime during reception 
of the first package
and during reception of the last

When i use 'softflowd' software sensor - all OK (see below), but when i use 
pflow interface 
then in fields FIRST and LAST i see huge values.
Maybe somebody knows, what mean these values ?


2:56 PM, up 3 mins - flow collection begin with softflowd

UNIX_SECS=1244458921 # 2009-06-08 15:02:01 +04
SYSUPTIME=363460     # 363460/1000/60 = 6 mins
FIRST=60073           # 
LAST=60090            #
