<P> The Canadian province of Saskatchewan is geographically located in the Mountain Time Zone . However, most of the province observes Central Standard Time year - round . As a result, it is effectively on daylight saving time (DST) year round, as clocks are not turned back an hour in autumn when most jurisdictions return to standard time . </P> <P> The city of Lloydminster is the only exception to this arrangement . Located partly in Saskatchewan and partly in Alberta, it observes Mountain Time year - round, and changes its clocks for DST . Since Lloydminster does change its clocks, the time in Saskatchewan is the same in all parts of the province during the summer months . </P> <P> During the summer, clocks in the entire province match those of Calgary and Edmonton . During the winter, clocks in most of the province outside Lloydminster match those of Winnipeg . </P> <P> In 1912, the first law was passed that called for the use of standard time . This law left the choice of time zone up to the municipal government . The result was a patchwork of towns following either of the two neighbouring time zones (Mountain Standard Time or Central Standard Time) with or without daylight saving time . </P>
