Change am/pm to a.m./p.m. in Drupal/ProsePoint?

@News_designJan 16.2010

First, a caveat: My knowledge of PHP is minimal at best at the moment; I have bought a couple of books, which I am starting to read through, but I feel like I’m still in the “learning my ABCs” stage … definitely not fluent in PHP yet.

I am designing a test site in ProsePoint (Drupal), and I would like for times to display as a.m. and p.m. instead of the PHP default of am and pm.

I did some research online about this a few weeks ago, and I stumbled across some script or bit of freeware that someone had written for just such a purpose … but now I can’t find it again.

And even if I did … I’m not quite sure where in the ProsePoint/Drupal installation I might need to put it in order for it to work.

Any ideas or suggestions?

@JerailJan 16.2010 — #You could do something like this:
[code=php]$meridian = (date('a') == 'am') ? 'a.m.' : 'p.m.';[/code]
As far as I know, that would be simplest way to do it, and then you could display your time like this:
[code=php]echo date('g:i ') . $meridian;[/code]

I think this should work. Perhaps somebody else would know a more efficient way of doing it.

@News_designauthorJan 17.2010 — #Thanks. That looks like it may take care of half the solution: the "how." My next task is to figure out the other half: the "where." Because I'm not fluent in PHP, it may take me a while to figure out where in all the PHP files that make up the site that information needs to go in order to work correctly.

Maybe I can find someone on one of the Drupal forums that can help me with that.

Thanks again for your help!

@News_designauthorJan 18.2010 — #Okay, the module in Drupal responsible for handling dates is Date API. I don't know enough PHP to really know what I'm looking at (or looking for), but I did discover this list of "cases" in the date_api_elements.inc file:

[CODE]$final_date = array('hour' => 0, 'minute' => 0, 'second' => 0,
 'month' => 0, 'day' => 0, 'year' => 0);
 foreach ($letters as $i => $letter) {
 $value = $values[$i];
 switch ($letter) {
 case 'd':
 case 'j':
 $final_date['day'] = intval($value);
 break;
 case 'n':
 case 'm':
 $final_date['month'] = intval($value);
 break;
 case 'F':
 $array_month_long = array_flip(date_month_names());
 $final_date['month'] = $array_month_long[$value];
 break;
 case 'M':
 $array_month = array_flip(date_month_names_abbr());
 $final_date['month'] = $array_month[$value];
 break;
 case 'Y':
 case 'y':
 $year = $value;
 // if no century, we add the current one ("06" => "2006")
 $final_date['year'] = str_pad($year, 4, substr(date("Y"), 0, 2), STR_PAD_LEFT);
 break;
 case 'a':
 case 'A':
 $ampm = strtolower($value);
 break;
 case 'g':
 case 'h':
 case 'G':
 case 'H':
 $final_date['hour'] = intval($value);
 break;
 case 'i':
 $final_date['minute'] = intval($value);
 break;
 case 's':
 $final_date['second'] = intval($value);
 break;
 case 'U':
 return date_convert($value, DATE_UNIX, DATE_DATETIME);
 break;
 }
 }
 if (isset($ampm) && $ampm == 'pm' && $final_date['hour'] < 12) {
 $final_date['hour'] += 12;
 }
 elseif (isset($ampm) && $ampm == 'am' && $final_date['hour'] == 12) {
 $final_date['hour'] -= 12;
 }[/CODE]

I'm wondering if it might be possible to adjust something in here to set up the "a.m./p.m." display. Am I looking in the right place? Or do I need to keep looking?

@JerailJan 18.2010 — #I don't know anything about Drupal, but as long as you back up your files, there's no harm in playing around with the code a little. Try doing this, and see what happens:

[code=php]  if (isset($ampm) && $ampm == 'pm' && $final_date['hour'] < 12) {
 $final_date['hour'] += 12;
 $ampm = 'p.m.';
 }
 elseif (isset($ampm) && $ampm == 'am' && $final_date['hour'] == 12) {
 $final_date['hour'] -= 12;
 $ampm = 'a.m.';
 }[/code]

@News_designauthorJan 18.2010 — #There are a number of lines related to am/pm in the module itself. Not being fluent in PHP, I'm not really sure what they all do, so I've copied them here. If you need more of the code (there's a LOT of code in the entire module), let me know.

That's all the references to am/pm in the module.
