Er, not to be a pedant, but why aren't you using PHP's built-in 
date/time functions?

check out date() and strtotime() to do what your shell commands 
currently do.  For example, here're a few lines from code I've written:

$now = strtotime("tomorrow");
$end = strtotime("Last Wednesday", $now);   // Today's last Wednesday

$thismonth = strtotime(date("m/01/Y"));

for($m = 0; $m < 12; $m++) {
  $s = ($m > 0) ? "s" : "";
  $t_month[(11 - $m)] = strtotime(date("m/d/Y", $thismonth) . " -$m 
month$s");
  $n_month[(11 - $m)] = date("M", $t_month[(11 - $m)]);
}


strtotime is pretty good at understanding English descriptions of 
moments in time, and date() can take a ton of arguments to format a 
date/time stamp.
