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.
