In what government considered a compromise solution to establishing uniform time, effective April 27, , legislation was passed switching the entire province to CST until October, and MST for the winter months. The government chose not to enforce this legislation and the result was chaos as dozens of communities in the southeast refused to change to MST in the fall of One of the conclusions of the Time Committee was that "the observance of one uniform time throughout the province all year for instance, would work except that the people of the province will never agree on whether it should be Mountain or Central Time.
After much research, consultation and deliberation, the Time Committee's recommendations were submitted to Cabinet in May and formed the basis of the legislation to be implemented. In , Sir Sanford Fleming proposed a plan to standardize time that would divide the earth into 24 standard time zones.
Each of the time zones was to be one hour different from neighbouring zones. Each zone was defined equally on either side of a standard meridian. 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. In Canada , this time zone includes all of Manitoba , nearly all of Saskatchewan , a little part of western Ontario , and part of Nunavut most of the Kivalliq Region and part of the Qikiqtaaluk Region.
Most of Mexico belongs to the Central Time Zone. The six northwestern states are not part of the time zone. In Oceania, the Chilean Easter Island also belongs to this time zone. Daylight saving time occurs from the second Sunday of March to the first Sunday of November. Most of the locations in Central Time Zone observe daylight saving time.
The pacific island of Galapagos near Ecuador falls into this time zone, which is six hours behind UTC. This is a military time zone used in aviation and is used at sea between the longitudes of This modification is UTC instead of the normal six hour offset.
As mentioned earlier, the Canadian province of Saskatchewan does not participate in this practice. Most of this example province is geographically located in the Mountain Time Zone, so by moving into the CST Zone, they essentially placed themselves on a permanent Daylight Saving Time.
In locations where DST is observed, the clocks change from local time to local time on the second Sunday in March. On the first Sunday in November, the clocks go from to Mexico has a slight change to this formula and changes their time on the first Sunday in April and the last Sunday in October.
Some of the border cities adopted the U. DST schedule after gaining approval from the government in The United States is composed of four separate time zones, which makes timing and scheduling for television broadcasts more complicated. In most cases, television networks will have two separate feeds that go to their owned-and-operated stations and affiliates.
The same process is true in the case of cable and satellite channels. This tape-delay is used for a variety of other purposes as well. For live broadcasts it is delayed seven seconds to account for possible profanity, bloopers, violence, or other things that would need to be censored. This delay allows programs to air at the same time in different zones. A show that begins at 8 P.
M on the east coast can also air at 8 P. M on the west coast through a tape-delay. The Mountain Time Zone complicates things further as it is sometimes given its own feed or a mixture of the east and west variations. M for Eastern and Pacific Time. It essentially removed an hour from the Monday through Saturday schedule, making it two hours, and three hours on Sundays.
