问题
We have a simple application in which we have all user in same timezone & therefore we are not interested to store timezone information in mongo date object.
Reason for such extreme step is we have multiple micro service using common database managed by different developers. Each of them requires to explicitly set timezone related stuff in query & forgetting same results in invalid dataset.
Since currently MongoDB folks Mongo Data Types
doesn't support storing dates without timezone.
Just eager to know that is their any alternative approach to represent date without timezone in mongo by which we can still able to take advantage of mongo database queries date based syntax like date ranges, date etc.
At the same time it would be convenient for DBA's to read and manage records.

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.

You could consider storing all the dates in UTC and presenting to the users in UTC, so you don't have the problem of silent conversion by either client JavaScript, server or MongoDB and therefore confusion. You can do it like this: new Date(Date.UTC(2000, 01, 28)) Here's MDN link on the subject.
