      Hi One of the varbind of snmptrap carrying date and time in Octet String. When i am trying to ocnvert it into string i got value that is not macthing the data and time. "DateAndTime (Octet String) (SIZE(8|11))"
      Here is my code


      $octets="D8 06 01 01 27 3B 00 ";

      @date = unpack 'n C6 a C2', $octets;

      $datetime = sprintf "%04d-%02d-%02d %02d:%02d:%02d", @date; # no time zone

      print $datetime

      $datetime = sprintf "%04d-%02d-%02d %02d:%02d:%02d.%d%s%02d:%02d", @date; # with tz info
      ~

        Well, your $octets only has 7 bytes in it, so it wouldn't pass the specs of "either 8 or 11 octets". Fiddling with it a bit suggests you dropped a "07" from the start: 
        # you presented the octets as a string of hex numbers.
# I'll do the same, then strip out the spaces, and pack
# it into binary format
$octets = "07 D8 06 01 01 27 3B 00";
$octets =~ s/ //g;
$octets = pack "H*", $octets;

# now $octets is in a form as you would get back from snmp,
# so we unpack with the template I gave earlier:
@date = unpack 'n C6 a C2', $octets;

# and print
$datetime = sprintf "%04d-%02d-%02d %02d:%02d:%02d", @date;
print $datetime;

        This prints: "2008-06-01 01:39:59".
