java read date from json

Hi I'm trying to read date from a JSON object. Date is written to the JSON as UTC milliseconds, but when I try to read it, informamtion is lost. JSON is giving the number 

"time":1526438700000

and

int value = jsonObj.getInt("time")

returns a different value. Could there be information loss converting long to int?

I am using the javax.json implementation. jsonObj is an object I get from a JsonArray. I don't think there's a getLong method. I tried casting to long, declaring value as long, same result. I think the problem is getInt()?

Your number is bigger than the maximum value that could be hold in an int (MAX_VALUE = 2147483647)

Try to get it as a long, as the max value is way bigger (MAX_VALUE = 9223372036854775807L).

With the javax.json library, you can get the long value through getJsonNumber method

jsonObj.getJsonNumber("time").longValue();
