Here are the commands youll need~\r
For the 2 blocks on the timing mechanism, the same command for both\r
/scoreboard players add @a[score_Timing_min=1] Time 1\r
\r
For the starting line tripwire use\r
/scoreboard players set @p Timing 1\r
\r
For the finish line use\r
/scoreboard players set @p Timing 0\r
\r
And for the reset use\r
/scoreboard players reset @p\r
\r
Edit 6/5/13\r
Forgot to add these vital commands~\r
The two objectives need to be set\r
/scoreboard objectives add Timing dummy\r
/scoreboard objectives add Time dummy\r
\r
Then we need to have the right score display correctly\r
\r
/scoreboard objectives setdisplay sidebar Time\r
\r
And finally, to shut off the laundry list scrolling as the command block is counting out the seconds.\r
/gamerule commandBlockOutput false\r
\r
Enjoy!
