Look at this answer: https://stackoverflow.com/a/6776273/6105830

You can use two types of long representation (milliseconds or format yyyyMMddHHmmss). These are the only ways to not store timezone and still be able to make range queries.

Unfortunately you lost some aggregation properties. But you can do something like keeping two representations and use them at opportune times.

UPDATE:

Do not store date as I said before. You will lost many and many features of MongoDB and also will be hard to perform major operators on date fields.

Newer versions of MongoDB has operators to deal with timezone, and it should be enough to work with ISOTime formats. My application was using my own suggestion to store date. Now I have to let my users select their TimeZone (company has grown and we need to expand to other countries). We are struggling to change all models to use timestamp instead of a normalized date format. For further more explore the link: https://docs.mongodb.com/manual/reference/method/Date/
