to follow. The only cities that chose not to match the rest of Saskatchewan's time zone were in the southwest, in the areas around Lloydminster and Swift Current. Part of Lloydminster spills into Alberta, which mandates the use of daylight saving time. In order to keep clocks synchronised throughout the city, Lloydminster chose to follow Alberta's practice of observing daylight saving time—effectively placing Lloydminster and the surrounding area on Mountain Time year-round. Swift Current and surrounding communities also observed Mountain Time until April 30, 1972, when they changed to match the rest of the province. With respect to some province-wide matters, such as provincial elections, Central Standard Time is effectively used province-wide. This means that during any provincial general election held when Daylight Saving Time is not in effect in Lloydminster, polls in that city will open and close an hour earlier local time compared to the rest of the province. For other matters (for example, liquor laws), the local time is always the effective time in Lloydminster. The town of Creighton which is across the border from the larger community of Flin Flon, Manitoba unofficially observes Central Daylight Time (CDT) with the rest of Manitoba. Unlike Lloydminster, Creighton's use of Central Daylight Time has no legal sanction at the provincial level. This has some interesting side effects—for example, liquor establishments in Creighton are able to stay open one hour later than establishments in Flin Flon whilst Central Daylight Time is in effect since a liquor establishment in Creighton can only be bound to observe Central Standard Time by provincial law. In the early part of the 21st century, discussion was renewed over whether Saskatchewan should change its clocks seasonally to be synchronised with other provinces' practice. By extension, the question was raised whether to return to the Mountain Time Zone (which would set clocks backward an hour in winter from their current observation), or to remain in the Central Time Zone (which would set clocks forward an hour in summer from their current observation, effectively enacting double Daylight Saving Time). Premier Brad Wall had pledged to hold a referendum in the 2011 provincial election, but he later decided against it, saying it would be a waste of money since polls consistently showed a strong majority favoured the status quo. Saskatchewan Time Zone Due to these discrepancies, many computer programs and major operating systems offer a distinct "Saskatchewan" option when
