Some Manitobans will be getting some extra sleep this weekend and others will be making sure you wake up on time.

On Sunday morning, it will be 1 a.m. twice. Manitobans will set their clock back one hour when the clock strikes 2 o'clock.

"Under the Official Time Act, daylight saving time ends on the first Sunday in November and resumes the second Sunday in March," the province says in a reminder.

Time is on the side of Christy Cabral, an owner/manager at Stewart's Horology. She is the daughter of the late Stewart Benzing, the shop's previous owner. Starting on Friday people will be coming in to get their watches changed, and she expects to see people all next week.

"We have a few clocks and watches that we will adjust the time on," Cabral says."It gets easy the more often you set them. It's not a problem.

She expects older people with digital watches to make up most of those visits.

"My husband is happy to have me there for the car clock and for the oven and microwave," she laughs.

At École Secondaire Sisler High School, the largest secondary school in Manitoba, Head Caretaker Junel Malapad and his team of a dozen caretakers are in charge of changing the school's 150 clocks.

"it is something that I don't know if we dread needing to do, but it is an extra thing that we have to do," Malapad says. "We all have our own areas to take care of and maintain, so each person will have to take care of their clocks in their specific areas."

They work from Friday evening to Monday morning changing them, spending a lot of time on time.

He estimates that they take an average of six minutes to change with some requiring extra ladder work and moving furniture. In all, he says it will take a combined 15 hours to change.

Malapad, who is a well-known ultramarathon runner, says some schools have clocks that would automatically change, but they are older and are becoming harder and harder to repair.
