Esteemed Monks,
My database wants me to generate a datetime in this format:
YYYYMMDDHHMMSS
Perl's localtime() function has annoyed me since the begining of time but i still use it to solve this problem. Anyone can think of a better/faster/prettier/shorter(golf) solution (not using DateTime etc.)?
#!/usr/bin/perl -w
use strict;
use Benchmark;
use POSIX;
Benchmark::cmpthese(100000, {
'Reference Implementation' => '
my @time = localtime();
my $time = sprintf("%04d%02d%02d%02d%02d%02d", $time[5] + 1900
+, $time[4] + 1, $time[3], $time[2], $time[1], $time[0]);
',
'Reverse Array' => '
my @time = localtime();
my $time = sprintf("%04d%02d%02d%02d%02d%02d", $time[5] + 1900
+, $time[4] + 1, reverse(@time[0 .. 3]));
',
'Shorter Array' => '
my @time = (localtime())[0 .. 5];
my $time = sprintf("%04d%02d%02d%02d%02d%02d", $time[5] + 1900
+, $time[4] + 1, $time[3], $time[2], $time[1], $time[0]);
',
'strftime by Joost' => '
my $time = strftime("%Y%m%d%H%S",localtime);
'
});
