I would (not) do: 
#!/usr/bin/perl -w
use strict;
package TieTimeArray;
sub TIEARRAY  { bless [], shift }
sub FETCH     {  (localtime)[$_[1]]  }
sub FETCHSIZE { 9 }
package main;
my @now; tie (@now, "TieTimeArray");
while (1) { local $"=' '; print "@now\n"; sleep 1;  }

It compile and works (sort of). Indeed we hit a problem with the array tie design. you can't ask array content as a whole, so we ask local time for each element of the array. We hit the problem that gray codes are designed to avoid (pointer pending) Suppose that thru one defererence of @now, we ask time at 3:00 59.99999 sec to get the seconds, than again a jiffy later at 3:01 0 sec to get the minutes. We will give as a result 3:01 59 sec. Not good when it is instead 3:01 0 sec

So this is not really a good approach. So consider it only as a rather silly example of array tie code. If you want to tie here, tie to scalar.
