TimeEvent and Track not capturing Duration Property

[ranuja-apps]

I am using mixpanel v3.0.5 and i have notice either timeEvent or track not working as per the intended.

  static startTimeTrack(eventName: TimeTrackTypes) {
    this.Instance.timeEvent(eventName);
  }
  static endTimeTrack(eventName: TimeTrackTypes) {
    this.Instance.track(eventName);
  }

This is my code for tracking and i am calling startTimeTrack first and then endTimeTrack but i am not seeing duration field set in the mixpanel portal.
