Why create_at time generated from mongodb is different from actual localtime time?-CodePudding

I am now using the default created_at feature given by nodejs and mongodb.

But the thing is the actual time i created is different from the value return from server when created.

 {
                "_id": "615dbc9580b0913c58e32f41",
                "createdAt": "2021-10-06T15:11:17.740Z",
                "note": "I discount because i am bored",
                "services": [
                    null,
                    null
                ],
                "items": [],
                "total_amount": 12000
            }

In the above example , The time i created is 2021-10-06 10:10pm bit there is a big differnet from the return date time which is 2021-10-06T15:11:17.740Z how can i change this behavior

CodePudding user response：

If you are in the America/Los_Angeles time zone (Pacific Daylight time in early October) your time 2021-10-06 22:10 is the same as 2021-10-06T15:10Z -- the Z means UTC.

So, if your diagnosis of the time shift is correct there's a one minute, seventeen second skew between the clock you used to get the 10:10pm time and the one that was used to generate the timestamp in your object.

Honestly, that seems unlikely. It's quite hard to rig a server these days without NTP time synchronization.
