Re: ISO Date Week Number

This is assuming your install of v5.0 has a working POSIX.pm:

use POSIX 'strftime';

# replace with actual date
my @localtime = qw/YYYY MM DD 00 00 00/;

# see perldoc -f localtime
$localtime[0] -= 1900;
$localtime[1] -= 1;

print strftime('%V', reverse @localtime);

From my copy of (perldoc POSIX): `If you want your code to be portable, your format ("fmt") argument should use only the conversion specifiers defined by the ANSI C standard. These are "aAbBcdHIjmMpSUwWxXyYZ%".` [download] I'm not familiar with the apparently non-standard `%V` code. Does that offer the "week number" as requested by the original poster? On what platform(s)? -- `[ e d @ h a l l e y . c c ]`	[reply] [d/l] [select]

Yes, it corresponds to ISO's standard definition of a week number. Tested on: Linux 2.4.21, Perl v5.6.1 Linux 2.6.10, Perl v5.8.3 Mac OS X Tiger 10.4.2, Perl v5.8.6 Of course, if the OP is still using v5.0 I've got no idea what kind of old OS they're using, so YMMV.	[reply]
