      Description

      I have some data which we transformed into json so it can be imported into mongodb.

      For some documents we need to have a date field that lies before 1970.

      Here I document this issue simply with 1 millisecond before and after epoch.

      We tested the documents by essentially doing this:

      [nbasjes@localhost ~]$ echo 'db.datetest.save({"date": new Date(1)});' | mongo nielsbasjes
      MongoDB shell version: 2.0.6
      connecting to: nielsbasjes
      bye

      [nbasjes@localhost ~]$ echo 'db.datetest.save({"date": new Date(-1)});' | mongo nielsbasjes
      MongoDB shell version: 2.0.6
      connecting to: nielsbasjes
      bye

      and two documents have been inserted.

      However when we try to load the same documents using mongoimport we get this:

      [nbasjes@localhost ~]$ echo '{"date": new Date(1)}' | mongoimport -vv -d nielsbasjes -c datetest
      Thu Jun 21 17:43:19 creating new connection to:127.0.0.1
      Thu Jun 21 17:43:19 BackgroundJob starting: ConnectBG
      Thu Jun 21 17:43:19 connected connection!
      connected to: 127.0.0.1
      Thu Jun 21 17:43:19 ns: nielsbasjes.datetest
      Thu Jun 21 17:43:19 filesize: 0
      Thu Jun 21 17:43:19 got line:{"date": new Date(1)}
      Thu Jun 21 17:43:19 got line:
      imported 1 objects

      So far so good ...

      [nbasjes@localhost ~]$ echo '{"date": new Date(-1)}' | mongoimport -vv -d nielsbasjes -c datetest

      We have tried several syntaxes for the same date and we get the same effect with all these forms:

      • {"date": new Date(-2174520376)}
      • {"date": new Date(1901,2,3,22,33,44,000)}
      • {"date": new Date("February 3, 1901 22:33:44")
