Hi,

Introducing myself as a very new beginner in perl so sorry for basic questions as always, but I always get the right answer in perlmonks and I love this place...

so heres my problem. I have a file output which I collect using perl. The output contains several lines of logs each with a timestamp. Now I need to process this output and print just one line out of the output. This line tat I want to print is based on the specific time of the day.

The challenge is the time is epoch time. I have to print say for example the line corresponding to 12:15 AM in the logs by parsing each line of epoch time, convert it to date/time format and then if it matches 12:15, print only that line from the log.

My idea was to import the epoch time into array, convert the epoch time to readable time, then do a condition match. But it turned out to be much more complex than that and I couldnt get it work.

Could someone help me. Here is a sample output: the big numbers like 1375976271 are the epoch time start and end. from this output I want to print the line matching a specific time.
