Answer 1

perhaps simply convert a date into string? this has less to do with mongo than js. moment is awesome but unusable in a mongo shell script.

db.events.find().forEach(function(doc) {     
   //   printjson ("Document is " + doc);    
   var isoDate = doc.t;   // t is correct key?     
   var isoString = isoDate.toISOString()    
   // update the collection with string using a new key    
   db.events.update({"_id":doc._id},{$set:{"iso_str":isoString} );
   // or overwrite using 't' key      db.events.update({"_id":doc._id},{$set:{"t":isoString} );
})
