Hi, can anyone explain in what format Date properties are returned over REST Api?

You can read more about this format here . Basically, Dates in SpiraTeam are represented in JSON as "\/Date(number of ticks)\/" . The number of ticks is a positive or negative long value that indicates the number of ticks (milliseconds) that have elapsed since midnight 01 January, 1970 UTC .

The problem with dates in JSON and JavaScript in general - is that theres no equivalent literal representation for dates. In JavaScript/ jQuery following Date constructor straight away converts the milliseconds since 1970 to Date as follows: var jsonDate = new Date(1297246301973); Then lets convert it to js format: var date = new Date(parseInt(jsonDate.substr(6))); The substr() function takes out the /Date( part, and the parseInt() function gets the integer and ignores the )/ at the end. The resulting number is passed into the Date constructor . For ISO-8601 formatted JSON dates, just pass the string into the Date constructor: var date = new Date(jsonDate); Mon, 19 Oct 2020 06:00:17 -04002020-10-19T06:00:17-04:00/Support/Forum/spirateam/issues-questions/1475.aspx#reply3863
