Timestamp like a text field?
MQTT Sensor would most likely be the way to go.

Something like this (untested) could work.
Assuming your sending something like this from your esp8266.

esp8266/ntp
{"_name":"esp8266ntp","timestamp":2016-06-07 05:30:18.063570}


sensor:
  platform: mqtt
  state_topic: "esp8266/ntp/"
  name: "Timestamp"
  value_template: '{{ value_json.timestamp }}'
