How is that extra responsibility? Do you think Snapchat aren't already running servers?
And you don't care whether the time on the server is running accurately if you're just using it to generate tokens which are checked against the time on the server. It just needs to be consistent, it could be an arbitrary counter and would still work fine as long as it counted up reliably at consistent intervals.
