Check the processing time

When creating a batch processing program, it is often the case that you want to know how long it took from the start of processing to the end of processing.

I would like to know how long it takes if I download a large zip file or insert a large amount of data into a database or the like.

In such a case, use time function to get the processing start time and hunting time to calculate the processing time.

# Start time
my $start_time = time;

# process
...

# ending time
my $end_time = time;

# Elapsed seconds
my $process_time = $end_time-$start_time;

print "$process_time\n";

You can calculate how long it took to process by subtracting the start time from the end time.
