populate times left with select boxes

I have a form that has a drop down menu for both a starting time plus an ending time.

The range of times is from 7:00am until 6:00pm, with a default start time at 07:30am an default end time at 04:00pm.

What I'm hoping to achieve through jQuery /Ajax is if the default start time is change to say 10:00am then the end time box would remove every time prior to 10:00am and only show from 10:15am until 6:00pm.

		<div id="row">
			<div id="left">
				<strong>Start Time:</strong>
			</div>
			<div id="right">
				<?php
					$start = strtotime('07:00 am');
					$end = strtotime('06:00 pm');

					$startDefault = $today . ' 07:30 AM';
					$startDefault = strtotime($startDefault);
					
					$postedStart = $today . ' ' . $_POST['startTime'];
					$postedStart = strtotime($postedStart);
					
					echo '<select name="startTime" class="fieldclasssm">';
					for ($i = $start; $i <= $end; $i += 900)
					{
					echo '<option value = "'.date('h:i A', $i).'"'; if(isset($submitRequest)  && $i == $postedStart) { echo "Selected = 'SELECTED'"; } elseif(!isset($submitRequest)  && $i == $startDefault) { echo "Selected = 'SELECTED'"; } echo '>' . date('h:i a', $i). '</option>';
					}
					echo '</select>';
				?>
			</div>
		</div>
		<div id="row">
			<div id="left">
				<strong>End Time:</strong>
			</div>
			<div id="right">
				<select name = "endTime" id = "endTime" class="fieldclasssm">
					
				</select>
				<?php
					$start = strtotime('07:00am');
					$end = strtotime('06:00pm');

					$default = $today . ' 04:00PM';
					$endDefault = strtotime($default);

					$postedEnd = $today . ' ' . $_POST['endTime'];
					$postedEnd = strtotime($postedEnd);
					
					echo '<select name="endTime" class="fieldclasssm">';
					for ($i = $start; $i <= $end; $i += 900)
					{
					echo '<option value = "'.date('h:i A', $i).'"'; if(isset($submitRequest) && $i == $postedEnd) { echo "Selected = 'SELECTED'"; } elseif(!isset($submitRequest)  && $i == $endDefault) { echo "Selected = 'SELECTED'"; } echo '>' . date('h:i a', $i). '</option>';
					}
					echo '</select>';
				?>
			</div>
		</div>

What is the actual HTML markup generated by your PHP script?  View the browser's source code, copy it, then paste it here.
