Converting string to datetime from jQueryUI datepicker using strtotime - php

Question

I am using jQueryUI datepicker and here is the code.
<link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
<link rel="stylesheet" href="/resources/demos/style.css">
<script>
$(function() {
$( "#from" ).datepicker({
defaultDate: "+1w",
changeMonth: true,
numberOfMonths: 3,
onClose: function( selectedDate ) {
$( "#to" ).datepicker( "option", "minDate", selectedDate );
}
});
$( "#to" ).datepicker({
defaultDate: "+1w",
changeMonth: true,
numberOfMonths: 3,
onClose: function( selectedDate ) {
$( "#from" ).datepicker( "option", "maxDate", selectedDate );
}
});
});
</script>
<form action="{LINKTO_EXPORT}" method="post">
<h1>{EXPORT_CSV}</h1>
<label for="from">from</label>
<input type="text" id="from" name="from">
<label for="to">to</label>
<input type="text" id="to" name="to">
<input type="submit" value="{EXPORT_TEXT}">
</form>
When I "post" the "from" and "to",
$fromstr = $_POST["from"];
$tostr = $_POST["to"];
$from = date('Y-m-d H:i:s',strtotime($fromstr." 02:00:00"));
$to = date('Y-m-d H:i:s',strtotime($tostr." 02:00:00"));
the to has been converted properly, i.e., 2015-06-13 02:00:00 but the from has not. It returned 6/1/2015 2:00 instead. To make sure I am fetching the correct values, I echoed the $fromstr and $tostr.
$fromstr returned 6/1/2015
$tostr returned 06/13/2015
Why was the from returned m/d/yyyy while to did mm/dd/yyyy? How do I convert a m/d/yyyy string to timestamp then? Please help, thank you!

Try this..
Download following js
<link rel="stylesheet" type="text/css" href="http://xdsoft.net/scripts/jquery.datetimepicker.css"/>
<script src="http://xdsoft.net/scripts/jquery.datetimepicker.js"></script>
You cant use directly ,so download js and css.
<script>
$(function() {
$('#datetimepicker8').datetimepicker({
onGenerate:function( ct ){
$(this).find('.xdsoft_date')
.toggleClass('xdsoft_disabled');
},
minDate:'-1970/01/2',
maxDate:'+1970/01/2',
timepicker:false
});
$('#datetimepicker9').datetimepicker({
onGenerate:function( ct ){
$(this).find('.xdsoft_date')
.toggleClass('xdsoft_disabled');
},
minDate:'-1970/01/2',
maxDate:'+1970/01/2',
timepicker:false
});
});
</script>
<input type="text" id="datetimepicker8"/>
<input type="text" id="datetimepicker9"/>
