Hi vino,

Posts are similar but the first one was in the year "2006".

This is not a home work.

I am writing a unix program which will generate a report of a process.The process is having two logs the start.log(time of start of process )and the end.log(end time of the process).

I want in my report to show the over all time of the process for that i will have to subtract the end time from start time.
I know to fetch the data from the logs.
Now i want to subtract the two dates.
The datecalc is also not working as this invloves characters.
Request expert help.
