If an Action is added to the ToDo List, the database stores the Application Server's time.

double estimate = (Double.parseDouble(estFinalActivity) * (newFermHr)) / (Float.parseFloat(fermDays) * 24);
// limits the precision of the estimate to 2 decimal places
double newEstimate = rint(estimate, 2);
//Sets up and executes AddSDI Action
HashMap hm = new HashMap();
hm.put("sdcid", "Ferm_Details");
hm.put("estimate", String.valueOf(newEstimate));//this is the pratfall
hm.put("ferm_masterid", keyId);
ab.setAction("addSDI" + i, "AddSDI", "1", hm);

To make this locale-sensitive, use connectionInfo to provide the "estimate" value (an instance of the connectionInto object contains connection information for the user):

hm.put("estimate", sapphire.util.FormatUtil.getInstance( connectionInfo ).format( new BigDecimal( newEstimate ) ) );

SimpleDateFormat format = new SimpleDateFormat("MM/dd/yy hh:mm:ss aaa");
String getSamplingDate = df1.format(sdf.parse(samplingStart));//samplingStart from user input
Date date1 = format.parse(samplingStart);
Calendar c = Calendar.getInstance();
c.setTime(date1);
Date dt1 = c.getTime();

function calculateSum( fieldAid, fieldBid, sumfieldid ) {

fieldA = document.getElementById( fieldAid );

fieldB = document.getElementById( fieldBid );

fieldSum = document.getElementById( sumfieldid );

if ( fieldA.value.length > 0 && fieldB.value.length > 0 ) {

numA = fieldA.value.replace( decimalSeparator, '.' );

numB = fieldB.value.replace( decimalSeparator, '.' );

sum = new Number( numA ) + new Number( numB );

//skipped need to feature out precision

sum = sum.toFixed( 2 );

//format back

fieldSum.value = new String(sum).replace( '.', decimalSeparator );

}

}

The problem here is that a round-trip to the Application Server is required to convert locale and time zone. This is far too complex to code in a JavaScript function.

The JavaScript (client-side):

document.write( "<div style=\"display:none\" id=\"validationDiv\"></div>" );

function calculateDueDate( requestDate, dueDateFieldId ) {

//document.getElementById( dueDateFieldId ).value = requestDate;
//If you tried the previous line, you would have to add 7 days and 8 hours, then consider that the user's locale and time zone be properly formatted. This is too complex for JavaScript... it has to go server-side...
document.getElementById( dueDateFieldId ).className = 'ValidationFail';
src = 'rc?command=file&file=CalculateDate.jsp&requestDate=' + requestDate + '&dueDateFieldId=' + dueDateFieldId;
//The adventurous could also use AJAX here.
document.getElementById( "validationDiv" ).innerHTML = "<iframe style=\"display:none\" id=\"validationFrame\" src=\"" + src + "\"></iframe>";

The JSP (server-side):

<sapphire:page>

<% //Construct locale timezone DataSet object
ConnectionProcessor cp = pageinfo.getConnectionProcessor();
DataSet ds = new DataSet( cp.getConnectionInfo( cp.getConnectionid() ) );
//parse input field into calendar object
ds.addColumn( "date", DataSet.DATE );
ds.addRow();
ds.setValue( 0, "date", request.getParameter( "requestDate" ) );
Calendar newDate = ds.getCalendar( 0, "date" );
//calculate duedt
newDate.add( Calendar.DATE, 7 );
newDate.add( Calendar.HOUR, 8 );
ds.setDate( 0, "date", newDate );
//render duedt to input field with correct locale and timezone
out.print( "<script>parent.document.getElementById('pr0_duedt').value = '" + ds.getValue( 0, "date" ) + "';" );
out.print( "\nparent.document.getElementById('pr0_duedt').className = ''" );
out.print( "</script>");
%>

</sapphire:page>

A user with Hindi locale and Asia/Calcutta time zone will then see this:
