I need to tweak this code that creates a csv file - Part II

The data that's going into the csv file is fine, but my user wants the posted time to read as mm/dd/yyyy h:mm:ss. Right now, it shows up as mm/dd/yyyy h:mm. I can change it manually, but is there a way I can dictate the way it's entered into the csv file? The data is sound, as far as it being in the database as 2014-03-07 22:56:59, but when it hits Excel, it's defaulting to a format that omits the seconds. How can I fix that?

Here's the code that I'm using right now:

$michelle="select actor_id, actor_display_name, posted_time, geo_coords_lat, geo_coords_lon, location_name from twitter_csv_test where geo_coords_lat BETWEEN '$lat_1' AND '$lat_2' and geo_coords_lon BETWEEN '$lon_2' and '$lon_1'";
$michelle_query=mysqli_query($cxn, $michelle);
if(!$michelle_query)
{
$rats=mysqli_errno($cxn).': '.mysqli_error($cxn);
die($rats);
}
$michelle_columns=mysqli_field_count($cxn);

//gets the field names from your table and sets them up as the first row in your csv file

$heading=mysqli_fetch_fields($michelle_query);

foreach ($heading as $val)
{
	$output .='"'.$val->name .'",';
}
$output .="\n";


while($michelle_row=mysqli_fetch_array($michelle_query))
{
	for($i=0; $i<$michelle_columns; $i++)
	{
		$output .='"'.$michelle_row["$i"].'",';
	}
$output .="\n";
}

$filename="twitter.csv";
header('Content-type:application/csv');
header('Content-Disposition: attachment; filename='.$filename);
echo $output;

I don't believe you can fix it from the server.  I think it's a setting in Excel.  When you generate a CSV file, it's got the data but that's about all.  The display format is controlled on the client's machine.

The only thing I could think to try on the server side would be to put it into single quotes.

In Excel, I highlighted a range of cells then did:
Right-Click -> Format Cells -> Number -> Date and did not find anything useful, however...

Right-Click -> Format Cells -> Number -> Custom looks promising.

I'll give it a shot, but I was wondering if that wasn't the case.

If I did try to put the data in single quotes, how would this change:

while($michelle_row=mysqli_fetch_array($michelle_query))
{
      for($i=0; $i<$michelle_columns; $i++)
      {
            $output .='"'.$michelle_row["$i"].'",';
      }
$output .="\n";
}

Would '"'.$michelle_row["I"]."',';  become '''.$michelle["I"].'''?

And yes, I did the formatting and it looks fine. My end user isn't confident that his team is going to know how to do that and wanted to know if I could do it programmatically.

I'll show you the code change if you'll give us the test data.  I've been programming long enough to understand that programming without test data is just guessing!

Just tested the single quotes idea.  It didn't work - Excel assumed the quotes were part of the data and cannot use it as a date.  Sorry, but I think the end user is going to have to give his team a quick lesson on Excel.
