How to store timestamps? Are created and updated fields available automatically?

Asked 2010-09-16T13:46:33.123

What's the best way to store timestamps in MongoDB?

Which format is best:

# "created": { "d" : "2010-03-29", "t" : "20:15:34" }
# "created": "12343545234" # seconds since epoc
# "created": "2010-03-14T21:20:14+0000"

Is there a way to have MongoDB automatically set created and updated fields?

Created time is in the ObjectId but, as far as I know, you will have to update a updated field manually.

Example:

ObjectId("538141a9615760fd04ffef5f").getTimestamp()
