-1 Hour timestamp in Javascript
<p>i have the following timestamp : 1445086800 </p>

<p>I want to do - 1 hour on this timestamp. 
What is the best way to do this in javascript? 
The output needs to be a unix timestamp also. </p>

<p>Is there something like a strtotime() in javascript function?</p>

<p>Thanks.</p>
