Answers to that include: Keeping the Auditors happy Knowing that “everyone does it” - the vendor told them so Bragging rights (expensive hardware) Being unbothered by fighting with facilities for building penetrations and antenna mounts Misunderstanding the beauty and economy Dave Mills marvelous algorithms for consistent time based on multiple sources, even those connected via internet Unwillingness or inability to leverage other local resources capacity to run ntpd with minimal impact in order to have a good constellation of local NTP servers Willingness to farm out time service without doing a deep dive into why and how, just leaving the design to the appliance vendors This covers most of what I have encountered in providing enterprise time services for $dayjob+clients. I probably left out some significant points, but it has been a few years...
