I am trying to get unix time from a time string, and was (for a second) quite pleased with myself for coming up with

my $datestr = '2017-02-10 08:12:57';
my $unixtime = timelocal(reverse split /[:\s-]+/, $datestr);

But then it returns Unix time that is one month ahead of what I expected, and the reason is not obvious to me...

The docs say timelocal synopsis is

$time = timelocal( $sec, $min, $hour, $mday, $mon, $year );

I checked and I am feeding it the correct data in the correct order:

my ($sec, $min, $hour, $mday, $mon, $year) = reverse split /[:\s-]+/, 
+$datestr;
print "sec:$sec min:$min hr:$hour mday:$mday mon:$mon year:$year\n";

What am I missing?

Was missing that month range is 0-11...
