best way to store datetime in to mongodb?

I am curious to know what others are using for storing dates in MongoDB. I need to store dates like user_created, user_lastLogin, ...etc. Has anyone had any experiences in why one approach may be better than another?

the driver for your language should allow you to use that language's date type/object.
