How to send Playing Time to Google Leaderboard?

Hi @Ancy. I recently needed to do the same. Here is my result which works. Note: Make sure to report the time in milliseconds (So for me, I had to multiply my total time in seconds by 1000).

 private void PostTimeOnline() {
 
         if (PlayGamesPlatform.Instance.IsAuthenticated()) {
 
             // report total play time
             Social.ReportScore((long) (GameInfo.TimeTotalPlay * 1000), GPGSIds.leaderboard_playtime, (bool success) => {
                 if (!success) {
                     Debug.LogError("Error posting to leaderboard_playtime");
                 }
             });
         }
     }
