[time-nuts] Re: What everyday uses are there for accurate clocks?

[Hugh Blemings]

Hi,

I'm sure others can speak in more depth than I, but birtually all major 
cloud providers and/or services that make use of large datacentres 
(think Facebook, Instagram, Linkedin etc. if you want publicly aware 
examples) - will run their own NTP servers or other similar time 
standards to ensure their geographically dispersed systems have a shared 
understanding of what the time is.

This is crucial for things as mundane as consistent end user experience 
(who posted first?) to ensuring network security.

Cheers,
Hugh
