Default Timestamp

Every record sent to Mona is dated to a specific date and time which is set as the record's main timestamp. This timestamp is set in the following ways:

• When sending data to Mona, if a record hold a value for the key exportTimestamp. This key sets the main timestamp. When sending a number of messages for the same record (context_id), the exportTimestamp value sent in the latest message will override the previous values as this record's main timestamp.

• If no value is sent under the exportTimestamp key, the time of when this record's first message was sent will be set as the main timestamp. This can be overwritten by sending a value for exportTimestamp.
