ProTip: if you change your phone's date/time, you can post on the past or future (relays might block it).

if my event has a created_at in the future it will be available to be listed only when this datetime reaches?
On amethyst, yes.
depends on the relay and what policy it enforces about this
bitcoin allows something like 2 hours divergence for timestamps on blocks, technically it is ok if block times are not monotonic... but this is a flaw in a short block interval chain, that's how the Verge blockchain got timewarp attacked (stopping the clock and enabling an attacker to mint infinite coins with dozens of empty blocks with coinbases to addresses they control
and probably not be able to access a heap of websites due to time divergence and your TOTP 2FAs won't work
i had fun with this on my windows pc recently repeatedly because for whatever dumbass reason it kept setting the clock automatically to the wrong time
I used to do that with emails. Make it look like I replied right away, yet it was way after lol
Or the apps should be able to recognize the wrong date and time and request to update it before proceeding (like the web browsers).
so, date/time stamps are just inherently unreliable... that hadn't occurred to me, but it makes sense... good tip!
