Thanks for the suggestion. This is the Regex that I've come up with: 

if($_=~/Launching the JVM/){
/\-+ [A-Za-z]{3} (.*?) (.*?) (.*?)\:(.*?)\:(.*?) (\d+)::(\d+)::Launchi
+ng the JVM with following options/;

 if ( $1 eq "Jan") { $month= "01";}
 if ( $1 eq "Feb") { $month= "02";}
...
 if ( $1 eq "Dec") { $month= "12";}

 if ( $2 eq " 1") { $start_date= "01";}
 if ( $2 eq " 2") { $start_date= "02";}
...
 if ( $2 eq " 9") { $start_date= "09";}

 if ( $3 eq " 1") { $start_hour= "01";}
 if ( $3 eq " 2") { $start_hour= "02";}
...
 if ( $3 eq " 9") { $start_hour= "09";}

 if ( $4 eq "1") { $start_min= "01";}
 if ( $4 eq "2") { $start_min= "02";}
...
 if ( $4 eq "9") { $start_min= "09";}

 if ( $5 eq "1") { $start_sec= "01";}
 if ( $5 eq "2") { $start_sec= "02";}
...
 if ( $5 eq "9") { $start_sec= "09";}

print "App Start time is: $6-$month-$start_date $start_hour:$start_min
+:$start_sec\n";

However, it is failing to convert if the date / hour / min / sec is a single digit / character 0-9 and prints it something like:

$perl get_ts.pl

--------------------------------------

App Start time is: 2015-04- 8 1:51:20

--------------------------------------

Not sure what I am doing wrong. I tried replacing .*? to \d+ but still not getting the desired results.

Can you please suggest?
