问题 If I try to put a date field in a Document (BSON) and write it to Mongo, BSON writes it in UTC. For example, a date DateTime dateTime = new DateTime("2015-07-01"); Document doc = new Document("date", dateTime.toDate()); will be stored as "date" : ISODate("2015-06-30T18:30:00Z") in Mongo. And, if I retrieve it using the same Java Driver I get it as Wed Jul 01 00:00:00 IST 2015 Great. Is there no solution to this? I mean, why can't I store my date as I want it?
