As an extra precaution, we examined the timing witness signals to ensure that the aLIGO datastreamís timing was perfect around Event Candidate G268556, alse referred to as GW170104, observed at 1167559936= Wed Jan 04 10:11:58 UTC 2017. We found that the DuoTone witness indicated excellent timing performance on the sub-microsecond level and the IRIG-B signals indicated precise second decoding.
