it's the only one that works IMO.

Yes, since the failure scenarios inherent in ensuring that context is
provided when asking the user for a date, ensures that the user is
involved in correctly providing the time.  The proposal that removes
this requirement that the author be actively involved and leaves the
server in much more unknown situation.

Oh dear, that's much worse!  That means neither the user, nor the
phone knows the right time in UTC terms!  - I don't change my phone
clock when I travel generally, so it's currently on UTC+1 time, it was
still that when I was in norway last week, but you're saying the phone
would've thought it was on UTC+2 because I was on a Norwegian network?
 That's very alarming news, and I'm very surprised it does that unless
it also updates the clock

Except this is a solved problem on the web IME (which is why I'm
asking for the use-cases)

Of course not, unless it's set the context for me to specify the time.
 That's what happens now, and what works now, I do not believe
introducing something I'm not even in control of (the timezone
information on my phone!) is going to simplify things.
