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

Mongodb 4.0 has introduced $toDate aggregation, so you can try with it

db.collection.aggregate([
  { "$project": {
    "toDate": {
      "$toDate": "$unixTimestamp"
    }
  }}
])
