<p>one can measure time between "start" and "end". What about measuring the time between specific keystrokes?

2,085,691 | 2,085,692 | Trying to convert from seconds to date | <p>Okay so I have an array of results from a table, we have a start and end time we are retrieving. the start/end time would look something like this: </p>
<pre><code>1345497551
</code></pre>
<p>Now I'm trying to convert this to a real time, for instance <code>1345497551</code> might become <code>2012/05/09 17:23:12</code> or something. I've found a few things but none seem to work correctly. one solution I tried, according to what someone was saying on another question on here, was </p>
<pre><code>$createdate = date('H:i:s',$numberofsecs);
</code></pre>
<p>where <code>$numberofsecs</code> was the time pulled in from the array. but this only ever outputs <code>17:00:00</code> repeatedly for every time we had available for testing. </p>

3,572,342 | 3,572,343 | What Android version to target? | <p>I'm about to write my first Android app. It's a fairly basic app that doesn't use any special features beyond being able to schedule notifications and read/write image files to the device's local storage. Reaching the broadest audience is my top priority. If I target Android 1.5, is the app guaranteed to run fine all the way up to ICS? Should I target Android 2.1, which seems to be the new baseline for common phones in use?</p>
<p>Since the app is fairly basic, if I target ICS, would it run on versions going all the way back to 2.1? Maybe this is a stupid question.</p>

However, in IE8, the rendered fonts (when animation is used) are thinner than the original font. I retried using .show(), now without the animation, and the rendered text was normal.</p>
<p>here's the jQuery code that handles the animation:</p>
<pre><code>var sibling = obj.next();
(sibling.is(":visible")) ? sibling.hide(100) : sibling.show(100);
</code></pre>
<p>where <strong><em>sibling</em></strong> is something like this:</p>
<pre><code><div class="tree">

<li><a>Item 1</a></li>
<li><a>Item 2</a></li>
<li><a>Item 3</a></li>
