# Negative Time Solving Contest 2012

## Partial Results

It's that time of the year again! This is your only chance of the year to solve a cube in negative time as day light saving (DST) ends and time falls back one hour. DST (Daylight Saving Time) ends in most parts of the United States and Canada, DST ends at 2am on Sunday, November 4. See Time and Date.com to check the clock change schedule in your area.

## The Contest

This challenge statement from 2004 by then-Caltech undergrad Tyson Mao pretty much explains it (original forum post).

 There is only one day of the year where one can leave the drudgery of Caltech academic life and sprint off for a chili burger, chili dog, and chili fries in a timely manner. A very timely manner indeed... so timely that one can actually return before he departs. This is the way of the Negative-Time Tommy's run. On one day of the year, a little bit before the first 2 AM, Caltech students hop in their cars and make a dash for the original Tommy's in Beverly Hills for some items with a lot of chili. The goal is to simply return before you left. If you are skilled, you may attempt the trifecta which consists of the burger with extra chili, the hot dog with extra chili, and the fries with extra chili. Last year, I missed achieving negative time because of an accident on Highway 101. Our total time was 4 minutes. Of course, last year, I did achieve negative time cubing at a time of negative 59 minutes and 1 second. (I was not very fast back then.) I challenge all of you to take part in the negative time solving tradition. We will have a website with the one, yes only ONE scramble which you will use for this entire year. The date I believe will be October 31, 2004.

## The Rules

By submitting your time(s), you indicate your compliance to the following rules:

• Use the provided algorithm(s). As usual, take up to 15 seconds of inspection per solve.
• Begin every solve before daylight saving ends and complete every solve after it ends in your time zone. In the United States, for example, you must begin every solve (start the timer and turn the cube, not just inspection) before the first 2 AM and end every solve after the second 1 AM.
• Don't be an idiot! This is an unofficial contest. Please follow all rules you would when submitting a record to speedcubing.com.

For example, if you start at 1:59:55 and end at 1:00:07, record your time as -59 min 48 sec. Rule 2 means that you can compete in multiple events at the cost of some extra time in each of your solves (except one). A fun category would be "most cubes solved blindfolded in a negative time." The entire solve must be done within an hour, so you first have to decide on the number of cubes to attempt and think about when to start memorizing.

Thanks to Tyson Mao for bringing this great Caltech tradition to cubing. Good luck to everyone!
