Really short Javascript cube timer

[molarmanful]

You may have seen my other really short Javascript scrambler. Well, here's the really short Javascript timer! Source: https://gist.github.com/molarmanful/7b3f54efef4141959b4c. Any suggestions?

Woah! That is really short. Who can top that off?

Using an interval for a timer is not a good idea, as it gets inaccurate pretty quickly. Use the system's time instead (I'm sure this can be quite small as well)

I considered that approach; however, I decided to stick with intervals because they saved more bytes. Such is code golf...

EDIT: Okay, I decided to go with your approach. At least it's got accuracy.

if you hold one key down and then press another, everything breaks.

Fixed. Also got byte count down to 316 bytes.

Bump...

Got down to 261 bytes:

function z(){for(c=b=j=25,r=Math.random,s[i='innerHTML']='';j;c+b-5|c-m&&b-m?s[i]+="URFBLD"[j--,c=b,b=m]+" 2'"[0|r()*3]+" ":0)m=0|r()*6}z(),k=0,onkeyup=function(x){x.which^32||k?(clearInterval(T),z(),k=0):(S=new Date,k=1,T=setInterval("a[i]=(new Date-S)/1e3"))}

- Change all document.getElementById stuff to shorter variants.
- Use onkeyup.
- Change == to ^ and && to ||.
- Take out second setInterval parameter.

Any more suggestions for lowering byte count?

More saves (258):

function z(){for(c=b=j=25,r=Math.random,s[i='innerHTML']='';j;c+b-5|c-m&&b-m?s[i]+="URFBLD"[j--,c=b,b=m]+" 2'"[0|r()*3]+" ":0)m=0|r()*6}z(),k=0,onkeyup=function(x){x.which^32||k?(clearInterval(T),z()):(S=new Date,T=setInterval("a[i]=(new Date-S)/1e3"));k=!k}

-Just merged k=0 and k=1 into k=!k.

256 now:

function z(){for(c=b=j=25,r=Math.random,s[i='innerHTML']='';j;c+b-5|c-m&&b-m?s[i]+="URFBLD"[j--,c=b,b=m]+" 2'"[0|r()*3]+" ":0)m=0|r()*6}z(),k=onkeyup=function(x){x.which^32||k?(S=new Date,T=setInterval("a[i]=(new Date-S)/1e3")):(clearInterval(T),z());k=!k}

-Declare k with onkeyup.

Haha lol

Wait, I'm pretty sure that's not supposed to happen...
