Please provide the following information when requesting support.

Hardware - GPU (T4)
Hardware - CPU 4
Operating System ubuntu:20.04
Riva Version 2.0.0

The result of a simple test gives me the following timestamps

Result: alternatives {
  transcript: "good morning"
  words {
    start_time: 1306600
    end_time: 200
    word: "good"
  }
  words {
    start_time: 440
    end_time: 520
    word: "morning"
  }
}

The start_time of the first word is always 1306600. This seems to be a bug, I would expect the true start_time of the word.
