G'day spikeinc,

Here's a technique for doing what you want.

I couldn't find any instances of 12:15 in the data you provided; I've used 15:13 as it did appear a few times. You may want localtime instead of the gmtime I've used here (you didn't specify your requirements in this regard). The JSON decoding was straightforward. Check the Time::Piece documentation to see how I've used it and for ways to format the output (if that's what you want).

#!/usr/bin/env perl -l use strict; use warnings; use JSON; use Time::Piece; my $wanted_hour = 15; my $wanted_minute = 13; my $data = decode_json join '' => map { chomp; $_ } (<DATA>); for (@{$data->{aaData}}) { print "@$_" if is_wanted_time(@$_[0,1]); } sub is_wanted_time { for (@_) { my $t = gmtime $_; return 1 if $t->hour == $wanted_hour && $t->min == $wanted_min +ute; } return 0; } __DATA__ {"DisplayRecords":"12","Records":"12","sColumns":"startTime,endTime, remoteNode,srcIP,srcPort,destIP,destPort,egress,ingress","aaData":[["1 +375976271" ,"1375976430","LAN","D0:05:FE","",1093,"",1330," +1034,348", "0,0"],["1375976246","1375976404","LAN","D0:05:FE","",1092, +"172.20.28 .2",1327,"1034,348","0,0"],["1375976191","1375976381","LAN","D0:05:FE" +,"172.20.3 0.2",1091,"",1324,"1034,348","0,0"],["1375976171","13759763 +14","LAN", "D0:05:FE","",1090,"",1321,"1034,348","0,0"],["1 +375976144" ,"1375976302","LAN","D0:05:FE","",1089,"",1319," +1034,348", "0,0"],["1375975155","1375976089","LAN","D0:05:FE","",1085, +"172.20.28 .2",1278,"1034,348","0,0"],["1375975194","1375975352","LAN","D0:05:FE" +,"172.20.3 0.2",1086,"",1281,"1034,348","0,0"],["1375974693","13759748 +35","LAN", "D0:05:FE","",1083,"",1271,"1034,348","0,0"],["1 +375974668" ,"1375974827","LAN","D0:05:FE","",1081,"",1268," +1034,348", "0,0"],["1375974691","1375974821","LAN","D0:05:FE","",1082, +"172.20.28 .2",1270,"0,0","0,0"],["1375881371","1375881561","LAN","D0:05:FE","172 +.20.30.2", 1055,"",1122,"1034,348","0,0"],["1375881410","1375881540"," +LAN","E0:0 5:AE","",1056,"",1125,"0,0","0,0"]]}
