Is there a way to display timestamp in unix format to ISODate?

Question

We stored a date using unix timestamp in MongoDB, how do I get the date when I do the query? Is there a way to display timestamp in ISODate format?

Answer 1

In the Mongo console you can create a JavaScript Date object from a timestamp before the document is printed to the screen:

> db.stuff.find().forEach(function (doc) {
  doc["timestamp_field"] = new Date(doc["timestamp_field"])
  printjson(doc)
})

Be careful with that code, unlike a regular find() it will not page the results but print every matching document without pausing.
