report.pl does not report correct time if result file is copied

[at15]

I am using git to synchronous benchmark result from virtual box to the host because I want to track the changes I made to configuration files, however I found when run report.pl <result-file>, I got different result in vm and host. I don't know perl, but I believe the script is using the create time of the result file as the start time of the bechmark, which is only true when you don't copy the result file.

The code that print the date is here

    printf "\n********************************************************************************************************\n";
    printf "# File  : %-20s : %20s\n", $file,ctime((stat($file))[9]);

    print "# THESE ARE PARTIAL STATISTICS\n" if( $cf->getResultField("OSSim","reportName") =~ /signal/i );

A possible solution is to use the beginTime and EndTime in the result file, i.e.

#END Configuration used. Extracted from "esesc.conf":
OSSim:reportName=done
OSSim:beginTime=Tue Jan 24 20:12:21 2017

OSSim:endTime=Tue Jan 24 20:19:58 2017
