JavaScript日期为前一天，即一天-1

Question

I am trying to save a specific format date in mongodb, but its saving a day-1

Example -

db.test.insert({name: "test1", dob: new Date(1986, 11, 30)})

But it is saving the date as 29 December 1986 , let me know what I am doing wrong.

Also I tried the same at mongodb but thr too its saving as day - 1 ie a previous day.

Answer 1

Timezones will always be an issue.

var dob = new Date();
dob.setUTCFullYear(1986);
dob.setUTCMonth(11);
dob.setUTCDate(30);
dob.setUTCHours(12); // just to be extra safe :p
db.test.insert({name:"test1", dob:dob});
