If you would like to use a Calendar widget with the date fields in RT, you can do the following. All of the file changes were done under the local RT3 Mason overlay, which is `/usr/local/lib/rt3/html` on my machine (Fedora Core 4). Note that this functionality is native in 3.8. Also note that this is NOT a calendar for Custom Fields.

• Create a directory named `NoAuth/js`

cd /usr/local/lib/rt3/html
mkdir -p NoAuth/js

• Download jscalendar from dynarch.com. (DynArch Calendar page)
• Unpack the downloaded file in `NoAuth/js`, I also renamed it to remove the version number

cd NoAuth/js
unzip /tmp/jscalendar-1.0.zip
mv jscalendar-1.0 jscalendar

• Now, create a directory named `Elements` to modify the date selector

cd /usr/local/lib/rt3/html
mkdir -p Elements

• I started by copying the contents of the `Elements/SelectDate` file distributed with RT and then modified it. Here's the final result:

<INPUT ID="<%$Name%>" NAME="<%$Name%>" VALUE="<%$Default%>" size=<%$Size%>>
  <BUTTON TYPE="reset" id="<%$Name%>_date_button">Choose...</BUTTON>
  <SCRIPT TYPE="text/javascript">
  Calendar.setup({
      inputField: "<%$Name%>",
      ifFormat:   "%Y-%m-%d %H:%M",
      showsTime:  true,
      button:     "<%$Name%>_date_button",
  });
  </SCRIPT>
  
  <%init>
  unless ((defined $Default) or
      ($current <= 0)) {
      my ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) =
                                              localtime($current);
          $Default = sprintf("%04d-%02d-%02d %02d:%02d",
                             $year+1900,$mon+1,$mday,
                             $hour,$min);
  }
  
  unless ($Name) {
      $Name = $menu_prefix. "_Date";
  }
  </%init>
  
  <%args>
  
  $ShowTime => undef
  $menu_prefix=>''
  $current=>time
  $Default => undef
  $Name => undef
  $Size => 16
  </%args>
  
  

Now, all the date fields should have a "Choose..." button next to them that pops open a calendar widget. You may need to restart the web server to force Mason to refresh the code cache. You might also want to use a button with an image, but I leave that as an exercise for the reader.

COMMENTS: Edit

10 Nov 2006 Edit

Opera 8.54 reported syntax error, fixed by removing the "," at the end of the argument list in SelectDate, as follows:

<SCRIPT TYPE="text/javascript">
Calendar.setup({
    inputField: "<%$Name%>",
    ifFormat:   "%Y-%m-%d %H:%M",
    showsTime:  true,
    button:     "<%$Name%>_date_button"
});
</SCRIPT>

Also, installing this on rt 3.4.6 I had to add some links to the head of Header

    <link media="all" rel="stylesheet" href="<%$RT::WebPath%>/NoAuth/webrt.css" type="text/css" />

  + <script language="javascript" type="text/javascript" src="<%$RT::WebPath%>/NoAuth/js/jscalendar/calendar-setup.js"></script>
  +
   <script>
   function hideshow(num) {
       idstring = "element-" + num;
  
  
  

Which I did by copying Header to local/html/Elements/Header and then editing it.
