Thanks John, Yes i do not have year field. Year is not the problem i have to match only the date and time and that is working fine for me. I have problems in handling the time because first initial time and end time will be entered by the user but after how i can manipulate it because the time will increase by the addition of one minute and so on till the end of file. I thought a lot how to do it but did not get success. Yes in my second entry i made a mistake. It is increasing by one minute. For example : Start time End Time Number of times word found. First time in file Dec 5 09:02:01 Dec 5 09:03:00 10 Second entry Dec 5 09:03:01 Dec 5 09:04:00 5 Third entry Dec 5 09:04:01 Dec 5 09:05:00 3 I have 3 files (these are the log files of the system). These files have > date formate like this (Dec 5 09:02:01). > Most date fields also have the year but your's doesn't appear to. Are you assuming the current year for all dates? I need to read these files from from the first date(Dec 5 09:02:01) till > the last date (Dec 17 17:34:02) in the file. Then i have to search a word > between the time difference of one minute and i have to count that how many > times that word is present between these two time period. > > For example : > Start time End Time Number of times word found. > First time in file > Dec 5 09:02:01 Dec 5 09:03:00 10 > Second entry > Dec 5 09:03:01 Dec 5 09:03:00 5 > Third entry > Dec 5 09:04:01 Dec 5 09:04:00 3 > In your second and third examples the end time is less than the start time. How did that happen? and so on till the last entry of the date (Dec 17 17:34:02) > > How i can handle these dates.

Time::Local is just one module that can help you do that.
