Thanks a lot for your replies. I really appreciate your help.

However, unfortunately, I still have problems trying both ways...

@Igal Malka, I tried the script you provided, but it only checks for days (not times)... meaning that it doesn't capture the case when there is non-sequential times in the same day.

Code:

14-11-2014 05:23 
14-11-2014 05:24 
14-11-2014 05:25 
14-11-2014 05:26 
16-11-2014 13:01 
16-11-2014 13:02 
16-11-2014 13:03 
23-11-2014 03:00 
23-11-2014 05:24 
23-11-2014 05:25

When I tired the script, the result was the below:

Code:

14-11-2014,05:23,05:26,4
16-11-2014,13:01,13:03,3
23-11-2014,03:00,05:25,3

It checked only for the date and assumed that those are only 3 minutes (on 23-11-2014), where it is actually 1 minute at 03:00, and 2 minutes from 05:24 to 05:25.


@RudiC, I tried the script you provided, but unfortunately it gave me some error related to printf:

Code:

-bash: printf: `(': invalid format character
-bash: printf: `(': invalid format character
-bash: printf: `(': invalid format character
-bash: printf: `(': invalid format character
-bash: printf: `(': invalid format character
