title: How to get next Date with specific time in PHP
body: <p>I want to get the date with specific day and time in PHP, like i want the date of next day and time of 9.30 am i.e "2011-06-02 09:30:00". 
  the code i was using get to do that,   </p>
  
  <pre><code>&lt;?php
     $next_day_date = date("Y")."-".date("m")."-".(date("d")+1)."  09:30:00";
     $new_trig_time_stamp = strtotime($next_day_date);
     $trigger_date_time = date("Y-m-d H:i:s",$new_trig_time_stamp);
     echo $trigger_date_time;
  ?&gt;
  </code></pre>
  
  <p>the code above works fine but fails on 31 day, on 31st it returns "1970-01-01 05:30:00".
  Is there any other way to do so.</p>
