sWhy is iPhone IOS showing invalid date for momentjs

Question

I have a datepicker which was returning a moment object that was always in UTC timezone. I needed to do some logic on this date, but always wanted it in the users local timezone

Answer 1

Try wrapping up with String function

//strip submission date of timezone offset
let submission_date = moment(String(this.state.startDate),'YYYY-MM-DD hh:mm:ss a');
let last_date = moment(String(this.last_date),'YYYY-MM-DD hh:mm:ss a').diff(submission_date, 'days');

Safari engine has some unique way of processing/parsing the date object
