1. When inserted the date format (2015-08-01), in mongodb it shows as 2015-08-01T04:00:00.000Z, where i expected it to be 2015-08-01T00:00:00.000Z

source data type used data stage: Date target data type specified in mongoDB: Date


  1. Why 04:00:00 timestamp is coming even though source has only YYYY-MM-DD (without time-stamp)?
  2. Is this the normal behavior of mongodb?
  3. Is there any thing i can do to have only timestamp as T00.00.00.000Z at target?

My requirement is to not convert the date into string format.

Thanks for the inputs. i did some research and found that Universal Time Coordinated is 4 hours ahead of Eastern Daylight Time. Mongodb by default inserts the date in UTC format .So when mongo sees non-UTC format from sourc ( in YYYY-MM-DD) treating it as 12:00am EST , converts into UTC format by adding 4hrs to EDT and 5 hrs when day light savings starts.

hope this helps .
