Tools.json field question

[ubunibme]

It looks like the current cloud based tool libs, ie the ones you create yourself are downloadable as a zipped .json file. There is a:

"last_modified":1468774083104   field in there. This is an integer counting up from some starting point. What is that starting point, what are the units?

Hey @ubunibme!

That variable is the timestamp in what's known as "Epoch time" or "Unix time" which represents a point in time, defined as the number of seconds (in this case though, milliseconds) that have elapsed since January 1, 1970, minus the number of leap seconds (again, milliseconds in this case) that have occurred since then.

Assuming you are working in javascript, you can get the date from this value with the Date.setMilliseconds(); function.

var milliseconds = 1468774083104;
// Must set to 0, this sets the date to the epoch time 00:00:00:00 Jan 1, 1970
var d = new Date(0);
d.setMilliseconds(milliseconds);

// Result
d = Sun Jul 17 2016 08:48:03 GMT-0700 (Pacific Daylight Time)

If you are using another language, just google "convert Epoch time milliseconds to date python" (replace python with whatever language you are using).

Hope that helps,
