The extract-timestamp transformer extracts a timestamp from the payload of the data message and uses it as the timestamp for the data message. When this transformer is not used, the timestamp for the data message is set to the time that it arrived at Golioth's servers. Using the extract-timestamp transformer effectively allows for the device to set the timestamp.

Timestamps provided under any of the following keys in a JSON payload, or a payload that is converted to JSON at an earlier step in a pipeline, will be honored:

  • t
  • ts
  • time
  • timestamp

The timestamp field will be removed from the payload after it is set in the metadata of the event.
