How to insert a MongoDB document with a timestamp from the database server

Question

In Oracle, I could simply do this: ``` INSERT INTO myTable VALUES ('someValue',SYSTIMESTAMP); ``` That would insert two values into myTable, and one of them would be a timestamp based-on the database server's time. For MongoDB (via the Java driver) I've tried this: ``` myDoc.put("value","someValue"); myDoc.put("timestamp", new Date()); myCollection.insert(myDoc); ``` But that creates a timestamp based-on the client machine's time, not the database server's time. Is there a way to have MongoDB apply a timestamp to a document based-on the the database server time?

Accepted Answer

A little late to the game - but the recent releases of mongodb have $currentDate.

See http://docs.mongodb.org/manual/reference/operator/update/currentDate/
