PETITION FAVORING CENTRAL TIME
==============================
I request that the Department of Transportation issue a notice of proposed rulemaking (NPRM), which will solicit public comment, and schedule public hearings on the proposed time zone change for Indiana.

I respectfully petition the DOT to seriously consider moving Bartholomew County and the entire state of Indiana back to the Central time zone. When time zones were first enacted by Congress (Standard Time Act of 1918), the Central-Eastern line bisected Ohio, so the western half of Ohio and virtually all of Michigan and Kentucky fell within the natural boundaries of the Central time zone. All of Indiana was located in the Central time zone. This was because, with longitude ranging from 85 to 88 degrees, it falls well within the 15-degree range for Central time from 82.5 to 97.5 degrees longitude.

I think it would be less confusing for Indiana residents, as well as for the rest of the country, if as many Indiana counties as possible all observe the same time. Central time appears the most logical choice to me, from business as well as personal perspectives.

The primary selling point that Governor Daniels made for Indiana's switch to daylight saving time was to put Indiana in sync year-round with most of the rest of the United States. From this perspective, either Eastern or Central time would be equally advantageous -- we would still change our clocks with the rest of the country twice per year, and always be the same number of hours different from just anywhere else in the U.S. that observes Daylight Saving Time.

And the rest of the country is already accustomed to dealing with Indiana businesses on both Central and Eastern time for about six months of each year, so neither zone should require more of an adjustment for our business partners than the other.

Since 1963 or so, most of Indiana has been three hours ahead of the west coast from October through April, and two hours ahead through the summer. We have observed year-round Eastern Standard Time (UTC -0500), which based on our longitude, is equivalent to year-round Central Daylight Saving Time.

Being on Central time would serve the convenience of commerce by putting Indiana businesses at most two hours away from all of our customers and suppliers in the continental U.S., rather than being up to three hours different from the rest of the country on Eastern time. This would expand opportunities for business with the west coast, without harming our relations with the east coast, which is already accustomed to being one hour ahead of us half the year anyway.

Kevin Brinegar, President, Indiana Chamber of Commerce, points out that 39 percent of Indiana's exports are with states that observe Eastern DST. This implies that the remaining 61 percent is with states that lie west of Indiana, with whom our time difference would be the one hour less if we observed Central time.

Another argument for Central time is to align ourself most closely with the population center of the country. The mean center of population of the United States is in Missouri, and moving westward with every census.

One argument for Eastern time is that Indiana borders more states that are in the ETZ than the CTZ. However, counting states gives only a superficial assessment. Michigan, Ohio and part of Kentucky are in the ETZ. Illinois and the western part of Kentucky are in the CTZ. The shared border with ETZ states is approximately 400 miles, while the border shared with those in CTZ is approximately 390 miles. A difference of only ten miles makes this argument nearly pointless. And, even those parts of Michigan, Ohio, and Kentucky that currently observe eastern time where they border Indiana actually fall within the Central time zone according to their longitude as well.

Obviously, wherever a time zone boundary occurs, residents living near that boundary have to learn to live with it, so I see no compelling argument for or against Indiana's observing either time zone. It's just a question of whether residents on the west and south or those on the north and east sides of the state need to make the adjustment, and there are about as many miles of border affected either way.

Some worry that if Indiana is on Central time that we will not enjoy the benefit of Daylight Saving Time, but by observing year-round Eastern time while lying geographically in the Central zone, we were effectively already enjoying year-round Daylight Saving Time and would not lose out on the additional hour of summer evening sunlight by observing Central Daylight Saving Time. On Central time, we will continue to enjoy the same additional sunlight in the summer evenings -- about 1.5 hours more evening sun than morning sun per day on average, while gaining one hour additional morning sunlight during the late fall and winter months of the school year.

Some Indiana business people like being an hour behind when the stock markets in New York close, so they can leave work an hour earlier and spend more time with their family.

Drive-in theater owners also favor Central time because families can get home an hour earlier after a night at the movies.

After we have begun to observe Daylight Saving Time in 2007 on Sunday, March 11, it appears much more sensible to be on Central time and have the sun rising in Indianapolis at 7am rather than 8am and setting at 6:50pm rather than 7:50pm. This gives motorists commuting to work, and schoolchildren walking and catching buses to school, in the morning an additional hour for well-lit safe travel compared to Eastern Time.

In addition to the concern about children waiting outside in the dark for their school buses in the morning, many argue that sending children to bed while it's still daylight can be difficult and might even affect a child's performance at school.

Some point out that having to stay up later to watch television shows will be an inconvenience for many people, possibly even affecting their performance at work the following day.

On Central Daylight Time, we would still have 1.8 hours more evening sun than morning sun on March 12. Shifting the time by one hour is intended to give a net two surplus hours in the evening versus the morning, and this is about what we would have with Central Daylight Time. Eastern Daylight Time would effectively be double daylight time, with almost two hours shifted from morning to evening, giving 3.8 hours more evening sun than morning sun.

When the time zones were initially established in the United States, they were approximately 15 degrees wide, centered every on every even multiple of 15 degrees longitude. This layout had the effect of putting local mean time for every point in the country within 30 minutes of the standard time for its time zone.

Indianapolis is about 15 minutes east of the 90-degree central meridian for the Central zone, but about 45 minutes from the 75-degree central meridian for Eastern, making Central the obvious choice for the whole state.

If Indiana remains in the Eastern zone, I understand that we would be the only state in the U.S. that lies completely within the mathematical boundaries of one time zone (Central) and yet observes a different time zone.

Sincerely, Bill Starr
Bartholomew County resident
