Re: Recent NTP pool traffic increase

The Snapchat mobile app does not currently have a need to talk with NTP
servers, it was an error. Also, this afternoon we spun off NTP server
instances in Australia and South America to help with the load.

Thanks,
Jad

This was my thought actually, Apple does offer some time services as part
of the OS but it’s becoming common with larger / more popular apps to
provide some of these services internally.
Look at the FB app for example, there are a lot of “system” things they do
themselves due to the ability to control specifics. Users don’t want to
have to install a second “specialised app” for this either.

With regard to an ephemeral chat app requiring time sync, I can think of
quite a few use cases and mechanisms in the app that might require time
services.

Mostly out of curiosity, what was the reason for the change in the
Snapchat code, and what plans does Snap have for whatever reason
the NTP change was put in place?

From other comments in the thread, it sounds like the app was simply
linked against a broken version of a library....

But why is a chat app doing NTP at all?  it should rely on the OS, or
a specialized app, to keep local time accurate.
