I am working on a site that is using version 2.6 of the Esri JavaScript API. I have an info window that displays some date information, and the date is one day behind the date in the database.

For example:

If I identify a feature in ArcMap, the date returned is 8/15/2007. When I query for the same feature through the Rest endpoint I get 2007/08/15 00:00:00 UTC. When I identify the feature in the web application, the date returned is 8/14/2007.

In the JavaScript code I am formatting the date as follows:

${SALEDT:DateFormat(selector: 'date', fullYear: true)}

What is causing this, and what can I do to have the correct date returned?

Specify local: true in your date formatting function:

${SALEDT:DateFormat(selector: 'date', local: true, fullYear: true)}

Mintx's answer explains why you need to do this. More information on formatting info window/popup content is available in the help: Format info window content.

Edit: Use DateString, not DateFormat to specify the local option:

${SALEDT:DateString(local: true, hideTime: true)}

Edit 2: Thanks to the mods, here's the answer originally posted my Mintx that I refereced above:

You've got it mostly right, you just need to change the code to reflect the correct time zone. Since the feature you're reading from is a UTC timestamp, the JavaScript code is converting to your timezone, which (assuming you're in the US) will be 4 to 7 hours earlier than midnight of 8/15/2007, which is why it's returning one day earlier.

Edit 3: I threw together a quick, hacky way to do this with a custom formatting function: jsfiddle.net/yEkjm There is probably a better way to do this...I'm no expert on handling dates with JS.

  • Thanks Derek. I put local: true in the formatting function and am still getting dates one day behind. I verified that I have dojo.require("dojo.date.locale") - is there anything else I need? I verified that the setting/code isn't being cached. Feb 14, 2012 at 18:22

    That's my mistake, I used DateFormat in my answer and it should be DateString. I've edited my answer to show the correct syntax. Feb 14, 2012 at 21:30
  • I tried using DateString earlier today, but I need the date in mm/dd/yyyy format, and DateString returns the date as "Tue August 14 2007." Feb 14, 2012 at 22:33
  • @Tim if you want fine grained control over the date format, we're back to DateFormat. In my testing, features retrieved from a service that stores dates as UTC are automatically converted to the client's timezone when displayed. Feb 14, 2012 at 23:02
  • Thanks Derek. You're right, they are being converted to my time zone - that's why they're one day earlier. Is there a way to force the dates to be returned as UTC, since that date is the correct one? Feb 15, 2012 at 15:16
