RE: Recent NTP pool traffic increase

Perhaps the host OS' to which snapchat caters, don't all have a devent ntp subststem available?
I have vague recollections of some other software (I'm sure we all know which) implemented it's own malloc layer for 
every system it ran on, for less trivial reasons. ;)

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.

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.
