I am getting these erros... Trying simple code to work with time

I don't know what is wrong... I need to do simple date math code

./dateExample.pl: line 6: syntax error near unexpected token `('
./dateExample.pl: line 6: `my $time = time();'


Code line 6  is
my $time = time();


my code
===============


#/app/cawily/support/perl/bin/perl -w



my $time = time();


my $future_time = $time + (45 * 24 * 60 *60);
my ($second, $minute, $hour, $day, $month, $year, $dayOfWeek, $dayOfYear, $daylightSavings) = localtime($time);
my ($fsecond, $fminute, $fhour, $fday, $fmonth, $fyear, $fdayOfWeek, $fdayOfYear, $fdaylightSavings) = localtime($future_time);

$year += 1900;
$fyear += 1900;

print "$month/$day/$year\n";
print "$fmonth/$fday/$year\n";

Your $dayOfWeek variable tells you what day of the week it is. Here is a slightly modified version of your code that adjusts for zero-based months.
#!/app/cawily/support/perl/bin/perl -w

my $time = time();

my $future_time = $time + (45 * 24 * 60 *60);
my ($second, $minute, $hour, $day, $month, $year, $dayOfWeek, $dayOfYear, $daylightSavings) = localtime($time);
my ($fsecond, $fminute, $fhour, $fday, $fmonth, $fyear, $fdayOfWeek, $fdayOfYear, $fdaylightSavings) = localtime($future_time);

$year += 1900;
$fyear += 1900;

$month++;
$fmonth++;

my @days = ("Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat");

print "$days[$dayOfWeek] $month/$day/$year\n";
print "$days[$fdayOfWeek] $fmonth/$fday/$year\n";

Much easier to do

#!/app/cawily/support/perl/bin/perl -w
use POSIX 'strftime';
my $day = strftime '%a',localtime;
print "day is $day\n";

Will your db performance match your db growth?

In Percona’s white paper “Performance at Scale: Keeping Your Database on Its Toes,” we take a high-level approach to what you need to think about when planning for database scalability.

Sunday is 0.
You can define an array ahead of time and the
@dayofweek=("Sun","Mon",);
Etc.
Doing the same for months will reduce the overhead of including/referencing other functions.
