Getting Time Zone

[mak]

How can I find the time zone? The end result I need to figure out if the date/time is in daylight savings or not. I've found:

use POSIX (strftime);
 
($d = strftime("%z", localtime)) =~ s/(\d\d)(\d\d)/$1:$2/;
 
print "$d\n"; 

which gives me this error:

"Unquoted string "strftime" may clash with future reserved word at timezone.pl line 12."

But it does output "Eastern Daylight Time". Is there a better way to do this or is there a way I can remove the warning?

use POSIX qw(strftime);

That works! Thanks! What does the qw() mean?

[KevinADC]

qw = quote words

is the equivalent of:

use POSIX ("strftime");
