Meridians were placed every 15 degrees of longitude around the earth's surface. If a person were to measure the width of a time zone at a line of latitude in North America, it would average miles. This is an approximate measure since actual time zones have irregular boundaries. The difference is positive if the local time is later than UT and negative if it is earlier. A standard meridian is located at the centre of a time zone, and 7.
The degree standard meridian for MST runs approximately down the middle of the province, and 7. In February , Earl R. Milton was the only professional astronomer in Saskatchewan at that time. The report included a basic definition of time, the development of timekeeping, and the evolution of a standardized system of time zoning in use in North America.
Professor Milton concluded that the entire province of Saskatchewan should be using MST based on these considerations:. The further from a central meridian a location lies, the greater the clock error. Milton indicated "to be included in an idealized time zone, the clock error of any location must not exceed thirty minutes. It was not until that The Time Act was passed in the Saskatchewan legislature.
The "solution" was a refinement of the compromise, made to satisfy all interests and resulted in the rather unique situation that exists in Saskatchewan with respect to MST and CST. Time option areas generally correspond to school divisions within western Saskatchewan. Section 9 of The Time Act sets out specific requirements for establishing time option areas, and also establishes current time option areas for western Saskatchewan listed as a schedule to the Act.
In recent years, the majority of time option areas in western Saskatchewan have voted to observe CST throughout the year.
DST was implemented during the First and Second World Wars as an emergency wartime measure to save electricity and fuel. However its use has continued since the First World War in many areas, mainly during the summer months. DST is the adoption of the standard time of the adjacent time zone lying east of any location. The clock is advanced one hour or runs continually fast by one hour. When using DST, the sun rises one hour later, noon occurs one hour later and the sun sets one hour later than when using standard time calculated from the local time zone meridian.
For example, a. Eastern Standard Time is a. Eastern Daylight Time. Legislation regarding the use of DST is provincial. By remaining on CST all year, Saskatchewan is on one uniform time year round. This is to notify the receiver that there is, in fact, a time difference. The Central time zone is six hours behind the Coordinated Universal Time and also follows daylight savings times.
Emails from this time zone will reflect a in the header as a notification to the receiver that this is where the email originates. While both time zones are used in the same manner, to differentiate between time, they are not similar in any other ways. The Eastern time zone and the Central time zone are used to separate time based on geographical differences.
The Eastern time zone affects states that are off the coast of the Atlantic, parts of Canada, and the Caribbean. The Central time zone affects the states that are in-between the Eastern time zone and the Mountain time zone, parts of Canada, and a lot of Mexico. Difference Between Similar Terms and Objects.

There is no need to resubmit your comment. Today, time zones establish order and allow national and international systems to operate, but we have maintained a fragmented time map in large countries. In the U. The Pacific Time Zone lies along the western coast of North America, reaching north from the lower 48 states of the U. The western border of the Central Time Zone begins at the northwestern edge of North Dakota and extends jaggedly down to the northwestern edge of Texas, while the eastern edge descends from Lake Michigan in Indiana down through Florida along the line of the Georgia-Alabama border.
Central Time includes the entirety of one Canadian province and 10 U. The Central Time Zone does not follow such clear boundaries as the Pacific Time Zone, which roughly follows state lines.
