I am creating a custom data entry app in sharepoint using the CSOM. I need to update the default value of a datetime field, I can get the default value but the datetime is in UTC Format.

I need to convert it to whatever format the sharepoint server uses. I have tried using the SP.Web.RegionalSettings.get_Dateformat() method like so:

var context = SP.ClientContext.get_current();
regionalsettings = context.get_web().get_regionalSettings();   //global variable
context.executeQueryAsync(configLoaded, configFailed);

function configLoaded(){
var dateformat = regionalsettings.get_dateFormat();

but this just returns a 0 value every time

You can simply parse the date using Javascript Date object. If different cultures are being used, you have to get the culture being used and format it accordingly.

var date = oListItem.get_item('StartDate');
if(date) {
 date = new Date(date).format('MM/dd/yyyy');
 window.console && console.log(date);

var today = new Date();
oListItem.set_item('StartDate', today);
  • The problem is I dont know what culture is being used? I'm not updating a list, I'm just putting the default value in a textbox.. So I need to know the dateformat to use (I need to get the culture info from Sharepoint)

  • Do you have sites in languages other than English? If so, you have to take into account the culture.

  • There are many ways to get the culture: a. _spPageContextInfo.currentCultureName b. _spPageContextInfo.currentCultureName c. document.getElementsByTagName("html")[0].lang

You could utilize CSOM TimeZone.UTCToLocalTime method to convert the specified date from Coordinated Universal Time (UTC) to local time.



  var context = SP.ClientContext.get_current();
  var web = context.get_web();
  var regionalSettings = web.get_regionalSettings();

  var dueDate = new Date();  //set DueDate to [now]
  var localDueDate = regionalSettings.get_timeZone().utcToLocalTime(dueDate);

     function() {
