Hi,
First thank you for this great plugin !

I have an api that return time serie data as json objects, like this:

 "histogram": {
        "1630281600000": 32,
        "1629763200000": 21,
        "1629849600000": 60
      },

I can plug my data with the ~ operator but the date interpreted is wrong. It compute to something like "1635-05-02 00:00:00".

Thank to your test suite I found that it's a problem with how dayJs parse the string (https://day.js.org/docs/en/parse/string). I was able to fix it by adding a call to parseInt() before the value is given to dayJs.

Would you be interested in a PR with those changes ?

EDIT: Thinking a bit more about it, it could cause trouble if the string is a ISODate, I'm going to try and see how both cases can be handled.

Thanks for your attention.
