whisper.decode doesn't returns timestamps

[harveenchadha]

import whisper

model = whisper.load_model("../model/medium.pt")

# load audio and pad/trim it to fit 30 seconds
audio = whisper.load_audio("../test.wav")
audio = whisper.pad_or_trim(audio)


# make log-Mel spectrogram and move to the same device as the model
mel = whisper.log_mel_spectrogram(audio).to(model.device)

# decode the audio
options = whisper.DecodingOptions(fp16=False)
result = whisper.decode(model, mel, options)

# print the recognized text
print(result.text)

the result here doesn't contains word level timestamps. Any idea what am I missing?
