Using Roughtime service

I want to try out the new service that Cloudflare is offering? But I am to sure where to start? Has anybody else tried this out?

Can I use curl on the command line? Anybody?

Roughtime is somewhat of a replacement for NTP. It needs more of a system level executable, like ntp, to work.

Why are you interested in Routhtime over what you currently use?

This is the problem. I have an iOS app that relies on subscriptions. And I want to check when they launch it that the date hasn’t been changed, set say a month earlier.

Now I can simply [not so simple] write my own daemon to fetch the time, but was looking for find something more secure, a tad easier [less time consuming, complicated].

I was hoping that rough time from Cloudflare might be a good match.
