I have a script which is set to run 24/7. Every day, it will create a new logfile of actions performed that day. This is for reporting and tuning purposes, to make sure the script is running at maximum efficiency. The question I have is outlined in the code below: 
use strict;
use warnings;
use Class::Date qw(:errors date localdate gmdate now -DateParse -EnvC)
+;

my $start = date now; #start date of the program running in format YYY
+Y-MM-DD HH:MM:SS
my @split = split(/ /, $start); #get just the Year/Month/Day
open (FILE, ">>/my/directory/logfile-$split[0]"); #open our daily logf
+ile
print FILE "$start\n";

sub dailyTask{
    my $now = date now; #Get our current time
    my @split = split(/ /, $now);
    close FILE; #close the existing daily file, in production this wil
+l zip it into a running archive of daily files
    open (FILE, ">>/my/directory/logfile-$split[0]"); #open our new da
+ily file
}


while(1){
    my $test = date now; #date when we start the loop
    print "Start: $start\n"; #print our values, so I can see
    print "Test: $test\n";
    my $soon = $start + '1D'; #Adds 1 day onto the start date
    print "Soon: $soon\n";
    print FILE "$test\n";
    
    
    if($soon < $test){#Check if I've passed our start + 1 day
        print "It's soon, now!\n"; #If so, print our value
        $start = $test; #update the new start time
        dailyTask();
    }
    sleep(86400); #sleep until tomorrow
}

Essentially, what I'm not sure if is whether or not the <FILE> file handle will (a) be passed to the called subroutine, and (b) whether the newly defined file handle will persist outside the scope of the subroutine. What is marked above is the essence of what I'm trying to accomplish (obviously with all the additional logic stripped out, for readability). Does anyone have any suggestions, or should the code work as written? Thank you.
