Just for good marks and all.. when you are dealing with a regex expression that will match a whole line it is good form to use ^(matches the beginning of a line) and $(matches the end of a line) to speed processing. So your regex expression would change to:

/^\A(\S+) (\S+) (\S+) (\d+):$/;

Also, if you truly wanted $1 to be set you could do so by just executing the regex statement provided by MarkM.

So instead of: 

my($wday, $mon, $mday, $time, $year) =
        $var =~ /\A(\S+) (\S+) (\S+) (\d+):/;

it would just be 

$var =~ /\A(\S+) (\S+) (\S+) (\d+):/;

[download]
and $1 would be set equal to the first match

$2 to second

and so on

These are static/constant variables so to modify them you would have to assign them to a seperate variable as MarkM has done. If however you just need to display or store the results why generate additional variables?

If you are doing this over a large number of entries you also might want to look into optimizing your statements using the lookaheads (I think that is the correct term) which allow the regex expression to set a qualifier before attempting to match any further into the string/line/block, etc..

example 

(?:[SMTWF]) 
warning I know my syntax is off so please don't use this.

at the beginning of your regex string should help to quickly skip those lines which do not start with a capital letter from the days of the week, nifty huh?

Just my .02 cents since I love regex.
