Perl, time stamp issue. 60th minutes
Hi Guys,

Could you tell me how you can get the time stamp for 60th minutes?

Currently, we name our file using time stamp upto minutes and then add seconds at the end starting from 01.

And when the seconds reaches 60 we simply add 1 to the time stamp and reset the seconds to 00.

But the problem occurs when the minute hits 60.

For example, file name starts from

20090330225900.csv then goes to

20090330225959.csv.

Then instead of going to

20090330230000.csv it goes to

20090330226000.csv.


Following is the code,

Code:
  $seconds_count = 1;
  $date_r = `date +%Y%m%d%H%M`;
  $date_r = substr($date_r,0,-1);

  foreach $blahblah{

    if (length($seconds_count) == 1){
      $seconds_count = "0" . $seconds_count;
    }

    # Build up the filename
    $filename = "                  .
                $date_r                   .
                $seconds_count            .
                ".csv";

    $seconds_count++;

    if ($seconds_count > 59){
      $date_r = $date_r + 1;
      $seconds_count = 0;
    }


Do you recon the following would work?

Code:
    if ($seconds_count > 59){
      $date_r = `date +%Y%m%d%H%M`+ 1;
      $seconds_count = 0;
    }

RETURN VALUE

       pcap_set_tstamp_type() returns 0 on success if the specified time stamp type is expected to be supported by the capture device,	PCAP_WARN-
       ING_TSTAMP_TYPE_NOTSUP  on  success if the specified time stamp type is not supported by the capture device, PCAP_ERROR_ACTIVATED if called
       on a capture handle that has been activated, and PCAP_ERROR_CANTSET_TSTAMP_TYPE if the capture device  doesn't  support	setting  the  time
