I like it.

Maybe I'll mix up too much UI and implementation in my questions but
here they are:
- The blueprint mentions that "certain OSes set's the BIOS clock to the
local time". How would this interfere with the current proposal?
- Shouldn't we ask for the timezone first and then the time, or the
two things at the same time. Maybe that's what is already meant by the
"and" in "And the corresponding UI lets me choose my preferred timezone".
- Would people on Windows be asked for this every time or otherwise
have a wrong clock on Windows?
- How wrong the clock has to be to trigger that stuff? I read from my
current consensus:
- "valid-after 2015-05-18 11:00:00"
- "valid-until 2015-05-18 14:00:00"
If all consensus are valid during 3 hours, then having the clock off
by 10 minutes would trigger that stuff 1 out of 18 times (very roughly).
That sounds reasonable.
- How precise the clock must be set by the user to work? and to get
hidden services to work (that's advertised as the feature that needs the
most precise clock)? Would ±5 minutes work? If my computer's clock is
off, then I might have to fallback on a physical clock (let's say my
watch) which can often be ±5 minutes off.
PS: During the last LHF, someone asked for tasks in private and I
pointed her or him to Tails Clock. That was "farh" or something like
this. If I get to see this person again, I'll ask for updates.
