How to check if DST (Daylight Saving Time) is in effect, and if so, the offset?

Question

This is a bit of my JS code for which this is needed:

var secDiff = Math.abs(Math.round((utc_date-this.premiere_date)/1000));
this.years = this.calculateUnit         


        

Answer 1

ES6 Style

Math.min(...[0, 6].map(v => new Date(95, v, 1).getTimezoneOffset() * -1));
