[Nfdump-discuss] Nfdump Netflow v9 logs capture timestamp date as 1970-01-01 00:00:00.51658

[Akshay U. <aks...@gm...>]

Hi,

I am using nfdump/nfcapd version 1.6.13 for capturing and processing
netflow v9 logs.

I am seeing a number of records where the "Date first seen" is being
recorded as "1970-01-01 00:00:00.51658".

To give a sense of frequency of occurrence of such records, there are
~1,48,000 out of ~13,31,000 records captured over 4 hour period which have
invalid "Date first seen" value. Hence "Time Duration" and "Bits Per
Second" fields also have invalid value. For remaining records the "Date
first seen" field has correct time value.

Is this a known issue with nfdump/nfcapd? Appreciate help on how to further
investigate/fix this issue.

Thank you.
