The clock does not change until you either refresh the page you are on, or click onto another page.
there isnt riding levels on howrse anymore but there is objectives. got to profile--objectives
There is no clock. It does, though, follow roughly the same time as howrse.
The GMT clock is not broken. Just keep breeding your unis at 6:23 GMT on Howrse.
you can't. watch the clock that really has your time. i have a central time zone and my real clock is 5 hours behind the howrse clock
That's impossible to answer without knowing your personal timezone. GMT time zone conversions are easily accessible on google, or you can look at the clock on howrse and work it out.
by changing the time
No
at the moment, no, you don't. But the prizes for the objectives are constantly changing. You might get lucky.
save without changing and then change it to what you want it to be
that wont work
No. The only thing would be the clock and radio.
created the first wooden clock and inspired people to continue changing or developing the clock i guess
