This sample shows how to format the content of an info window using the date formatting functions added at version 2.2 of the ArcGIS API for JavaScript. You can format the info template content using one of the out-of-the box formatters or for more advanced options you can define a custom formatting function.
In this sample, the dates for each earthquake are formatted using the DateFormat option. In this code snippet, a date pattern is defined to display dates in a month, day, year format.
