Start the week the same as the rest of Drupal

Here's a patch...

- sets the weights of the day sections on the schedule node
- makes a rearranged copy of the schedule array prior to it being turned into a table, both for viewing and editing the schedule.

Just realized that I haven't fixed the drop-downs you get to add or edit a schedule item.
Drewish, do you think it needs handling as well?

Oh, and shawnc -- I'll try to look at letting a schedule item wrap round the end of the week for another patch later & file it as a separate issue.

I don't think it's possible to set the order everywhere just by changing dayhour.inc::station_day_name().
For example, in schedule.module at line 818, the order in which columns are put into the table comes from $node->schedule, so I've got to reorder of that array before the foreach loops on it.

However, ALSO setting the order in dayhour.inc::station_day_name() means that the drop-downs are right :)

I can't make a patch for dayhour.inc, I'm afraid -- CVS gives me the error 'cvs [update aborted]: tag `*' must start with a letter' which is greek to me.
Here's my altered version of station_day_name, in addition to the earlier patch:

function station_day_name($day = NULL) {
  static $days;
  
  if (!isset($days)) {
    $daysplain = array(
      0 => t('Sunday'),
      t('Monday'),
      t('Tuesday'),
      t('Wednesday'),
      t('Thursday'),
      t('Friday'),
      t('Saturday')
    );
    $dayoffset = variable_get('date_first_day', 0);
    for ($i=0; $i<7; $i++)
    {
      $days[($i + $dayoffset) %7] = $daysplain[($i + $dayoffset) %7];
    }
  }
  
  if ($day === NULL) {   
    return $days;
  }
  else {
    return $days[$day % 7];
  }
}

Yeah, that's pretty slick. It works perfectly for me.

By the way, I had a look at the way the Calendar and Date modules handle the week's start date. In calendar/calendar_api.inc, the function that's sort of equivalent to station_day_name() has a switch on the 'date_first_day' variable, and each case has the array of day names in a the different order... the code isn't not as nice to look at, and I have no idea which method is optimal. Just though I'd mention it though :)

Yeah, noticed that too but figured it was nitpicking :)

The other thing that doesn't work is the list of times on a program node.
I'll look at it once I'm back on HEAD.

Suppose a program is on every day of the week. The list on the program node always starts with Sunday -- if we're allowing the site admin to change the order of days on the schedule, perhaps we should change the order of the list here too.

Works great :)
