javascript - Does cloning a date object in different timezone preserve it's original timezone? -


i have date object coming server in utc tz.

i want date arithmetics on client add days etc , sent server.

does doing like:

var newdate = new date(date);          // cloning date in utc newdate.setdate(result.getdate() + 7); // expecting new date in utc

preserves original timezone ?

date objects not have timezones. of methods, getdate (as opposed getutcdate) or tostring use local timezone calculate result return.

so answer question, yes, sample code preserves original timezone. sure that, when serializing send server, use toisostring() (or tojson()) instead of tostring().
