I person the “comparative clip successful phrases” condition from different room.

I’ve tried the pursuing:

relation isoDate(msSinceEpoch) { var d = fresh Day(msSinceEpoch); instrument d.getUTCFullYear() + '-' + (d.getUTCMonth() + 1) + '-' + d.getUTCDate() + 'T' + d.getUTCHours() + ':' + d.getUTCMinutes() + ':' + d.getUTCSeconds(); } 

However that provides maine:

"2010-four-2T3:19" 

Location is already a relation known as toISOString():

var day = fresh Day(); day.toISOString(); //"2011-12-19T15:28:forty six.493Z" 

If, someway, you’re connected a browser that doesn’t activity it, I’ve acquired you lined:

``` if (!Day.prototype.toISOString) { (relation() { relation pad(figure) { var r = Drawstring(figure); if (r.dimension === 1) { r = 'zero' + r; } instrument r; } Day.prototype.toISOString = relation() { instrument this.getUTCFullYear() + '-' + pad(this.getUTCMonth() + 1) + '-' + pad(this.getUTCDate()) + 'T' + pad(this.getUTCHours()) + ':' + pad(this.getUTCMinutes()) + ':' + pad(this.getUTCSeconds()) + '.' + Drawstring((this.getUTCMilliseconds() / one thousand).toFixed(three)).piece(2, 5) + 'Z'; }; }()); } console.log(fresh Day().toISOString()) ```
