Ten days to the nanosecond - please allow for a reasonable, coarser granularity. And, you should be aware that the result depends on the time of day that you run the script unless you define to use e.g. "today midnight" for the comparison...
Try
Code:
awk 'BEGIN {D10 = (srand()-864000); split ("OLDER YOUNGER", FN)} {print $0 > (FN[1+($2/1E9 > D10)])} ' file

You may want to add the desired conversions of the fields as given above.

NAME
sendinpaths - Send Usenet Path: statistics via e-mail SYNOPSIS
sendinpaths [-cdhn] [-k keep-days] [-r report-days] [address [address ...]] DESCRIPTION
sendinpaths checks pathlog/path for ninpaths dump files, finds dump files generated in the past report-days days, makes sure they are valid by running ninpaths on each one and making sure the exit status is zero, and passes them to ninpaths to generate a cumulative report. By default, that report is mailed to the e-mail addresses configured at the beginning of this script (by default, only one address is configured: <top1000@anthologeek.net>) in order to supply the TOP1000 project with useful statistics. See <http://top1000.anthologeek.net/> for more information. When finished, sendinpaths deletes all dump files in pathlog/path that are older than keep-days days. For more information on how to set up ninpaths, see ninpaths(8). OPTIONS
-c When this flag is used, the report is also e-mailed, besides the default submission addresses or those given as command-line arguments, to the newsmaster's address set at configure time. -d Enables debug messages. -h Gives usage information. -k keep-days After having processed dump files, sendinpaths removes those that are older than keep-days days. The default is 0, that is to say to remove all dump files. Setting keep-days to another value can be useful for debugging purpose because it permits to keep a few dump files. -n Don't e-mail the report; instead, just print it to standard output. Don't delete old dump files. -r report-days Process dump files generated during the last report-days days. The default is 32, that is to say to process all the dump files that have been generated during the last 32 days (if, of course, they have not been deleted yet by a previous run of sendinpaths according to the value set by the -k flag). address ... E-mail the report to the mentioned address or addresses, instead of the default one. Several addresses can be used, separated by whitespace. For instance, for two adresses: sendinpaths pathsurvey@top1000.org top1000@anthologeek.net HISTORY
