javascript convert date in the future to timestamp

Question

I want to get the timestamp of one-year from now:

var oneYr = new Date();
oneYr.setYear((new Date()).getYear() + 1);

When I try to get the timestamp:

oneYr.getTime() /1000

I get -58351759111000 (not correct)

It's only working for date in the past.
Any idea how to get timestamp for future date?

Answer 1

Use getFullYear instead of getYear.

var oneYr = new Date();
oneYr.setYear((new Date()).getFullYear() + 1);
