in thread day of year calculation

1 less function call:

#!/usr/local/bin/perl use strict; sub dayofyear { my ($day1,$month,$year)=@_; my @cumul_d_in_m = (0,31,59,90,120,151,181,212,243,273,304,334,365); my $doy=$cumul_d_in_m[--$month]+$day1; return $doy if $month < 2; return $doy unless $year % 4 == 0; return ++$doy unless $year % 100 == 0; return $doy unless $year % 400 == 0; return ++$doy; } print dayofyear(10,3,2005)."\n"; print dayofyear(10,3,2004)."\n"; print dayofyear(10,2,2005)."\n"; print dayofyear(10,2,2004)."\n";

[TCLion]: I am breaking down the line and putting the date in the correct order during output
[TCLion]: at least that's the plan
[1nickt]: Corion this looks good, from the pod: "there are 9000+ variations that are detected correctly in the test files (see t/data/* for most of them). If you can think of any that I do not cover, please let me know."
[TCLion]: some moron put the date like this : Mon Feb 20 09:31:30 2017
[Corion]: 1nickt: Yes, the module sounds promising indeed
[1nickt]: "putting the date in correct order" how?
[Corion]: TCLion: Whee ;)
[TCLion]: need to put like this : 2017-02-20 09:30:53
[1nickt]: That's why I asked if you are using DateTime. It has a large number of supporting modules (the author likes the term 'eco-system') so if you are already creating a DateTime obj from your dates, this module would read in the mnoron-formatted 1s seamlessly
[TCLion]: when I put the date together it looks like : 2017-Feb-24 (month is the problem)
