Time zone boundaries have changed greatly since their original introduction and changes still occasionally occur. DOT issues press releases when these changes are made. Generally, time zone boundaries have tended to shift westward. Places on the eastern edge of a time zone can effectively move sunset an hour later (by the clock) by shifting to the time zone immediately to their east.
If they do so, the boundary of that zone is locally shifted to the west; the accumulation of such changes results in the long-term westward trend. The process is not inexorable, however, since the late sunrises experienced by such places during the winter may be regarded as too undesirable. Furthermore, under the law, the principal standard for deciding on a time zone change is the "convenience of commerce".
Time zones in the 20th century
Interestingly, many French maps showed zero degrees at Paris for many years despite the International Meridian Conference's outcomes in 1884. GMT was the universal reference standard – all other times being stated as so many hours ahead or behind it – but the French continued to treat Paris as the prime meridian until 1911. Even so, the French defined legal time as Paris Mean Time minus nine minutes and 21 seconds. In other words, this was the same time as GMT. France did not formally use to Coordinated Universal Time (UTC) as a reference to its standard time zone (UTC+1) until August in 1978 (Sheen, cited in Brannel Astronomy, n.d.).
Standard time, in terms of time zones, was not established in United States law until the Act of March 19, 1918, sometimes called the Standard Time Act. The act also established daylight saving time in the nation. Daylight saving time was repealed in 1919, but standard time in time zones remained in law, with the Interstate Commerce Commission (ICC) having the authority over time zone boundaries.
Many countries adopted hourly time zones by the late 1920s. Many nations today use standard time zones but some places adopt half-hour deviations from standard time or use quarter hour deviations. Moreover, countries such as China use a single time zone even though their territory extends beyond the 15 degrees of longitude.
How Many Time Zones?
Given a 24-hour day and 360 degrees of longitude around the Earth, it is obvious that the world's standard time zones have to be 15 degrees wide, on average. Some sources claim there are 24 standard time zones, while others say there are 25 time zones. The perspective of the number of time zones depends on the definition of a time zone versus the International Date Line. The world also has non-standard time zones.
Half Hour Time Zones

The advantages of shopping online are (1) zero traffic or commuting time (2) no need to stand in long checkout lines and (3) the ability to peruse dozens of shops to compare pricing (with a few keystrokes of due diligence). In addition, if you factor the convenience of online shopping it is a perfect synergy for savvy online consumers who maintain hectic schedules and are inclined to make the most efficient use of their time.
To capture the e-generation shopper in the competitive online shopping industry, the e-tailer requires a firm grasp of usability (to keep traffic on the site), search engine optimization (to get them there) as well as ways to to gauge trends, sales cycles, inventory management and all of the trappings that accompany e-commerce, enterprise and cycles of supply and demand.
In an ideal scenario, optimization would start with keyword refinement, on-page analysis of the content and site structure to create a laser-like focus for the site theme to appease the target audience. Additionally, identifying which click-triggers emotionally rouse the core consumer and weaving the call to action into every page without over-selling is equally as important.
Tackling these objectives from the planning stage as opposed to trying to remedy them after the fact is one way to gain a competitive advantage and outrank a competitor selling virtually the same items.
If your e-tailing / market plan does not factor search engines as a crucial contributor to your promotional plan, driving traffic would rely on off-line or paid online sponsored advertising. Dependency on platforms such as PPC alone could erode profit margins dramatically by comparison to organic search engine optimization. In this instance, the e-tailer is optimizing their pages for popular brands or niche or specialty items. The more mainstream something is, the more competitive the arena. It boils down to price point, value proposition and packaging for most as far as online shopping goes.
The Takeaway for E-tailers:
Having clearly delineated and optimized site architecture and enough topical content (unique product descriptions) can distinguish your site with spiders.
Use keyword rich categories instead of long CMS (content management system) gibberish URL strings such as ?973-21.aspx instead of websitename/products/category/even-more-descriptive-title/ which uses a topical naming convention which translates as a structured and organized boilerplate to assist search engines find semantically related material.
A simple mod-rewrite can handle this, or some tweaking to your shopping cart are enough to overcome this obstacle from the start. Also, make sure the sitemap is linked to every page product page in the template (or a sitemap for every sub folder / section), you can use it later to tie everything together and ensure that spiders can traverse the sites vast categories and pages.
Every page indexed in search engines is another page out there working on your behalf bringing potential customers back home to your site, or helping your site gain more authority under the auspices of link popularity.
It is no secret that purchasing and the power of preference has reached new heights as e-commerce is paving the way for millions of entrepreneurs to break free from traditional brick and mortar based retail outlets.
The Additional Benefits of Online / Off-line hybrids:
If you own a local business that features items that are in high demand, then a targeted online campaign could drive hordes of qualified walk in traffic to your storefront.
It depends on your preference, standing in a store waiting for walk in traffic as a result of location or using the online shopping hybrid and leveraging link building, content and promotion to increase the bottom line. The idea is, to have positioning for your brand using both. In either case, it boils down to the same thing, the swipe of a credit card, a payment in cash and a monetary transaction for a product in demand.
Despite the fact that online shopping has its sensory limitations (like trying to sell fragrances over the internet) or not having the ability to physically touch the merchandise does not preclude online shoppers from purchasing online.
It's only a matter of time before we see "hybrid retail / e-tail based stores" with the ability to order online and then simply pick up the item to go from a drive-through / delivery window.
If retailers wanted to add value they could create express checkout allowing the person to purchase online, the retailer would then pick and pack the items and have it available for convenient pickup (like a fast food restaurant) with the payment already processed online (while the consumer is in route). Even if you are in the parking lot ordering from your mobile device, you can see the value of a V.I.P. elite (skip the line) shopping service that allows you to Checkout Now!
Since millions of consumers already purchase online as a result of convenience and emotional impulse, adding value to the proposition with new processes to aid the transaction process are pure win / win solutions for all parties involved.
There are three facets to consider about shopping online (1) the reason why consumers want to purchase (branding, the cycles of desire and fulfillment) and (2) the search terms one would use to find the most relevant match and (3) the landing pages ability to convert.
E-tailers not only live or die by the trends in search, but having a firm grip on the who, what, where, when and how factor when assessing a markets strength can come in handy in the event that you are interested in setting up shop.
Knowing that a profitable niche site if populated, promoted and managed properly with engaging content, give-always, incentives and the like, coupled with social media, GEO specific targeting to maximize psychographic purchasing (knowing your niche) can equal tremendous profit margins at a fraction of the cost of traditional marketing.
