CLARKSVILLE, Ind. (WHAS11) -- This Sunday we will spring forward and start Daylight Saving Time. If you think it's tough changing all your clocks, be thankful you aren't in charge of changing one of the country's largest clocks in Clarksville, Indiana. Clark's Landing Facilities Manager Richard Jenkins gave us an insider look at how they keep the Colgate Clock going.

"It’s been here since 1924," said Jenkins.

The Colgate Clock has been a part of Clarksville's skyline for almost 100 years. You can see it in this 1965 picture from the University of Louisville's Photographic Archives.

"Everybody that was born and raised in this area knows the clock," said Jenkins.

It may be one of the area’s most recognizable clocks, but few people know it as well as Jenkins, who has been keeping the clock going for the past 16 years.

While many people will be paying more attention to their timepieces with the start of Daylight Saving Time this weekend, this 40 foot wide clock is reset every week. Jenkins says changing the hour and minute hands takes quite a few helping hands.

"It takes three people, one to pull the pin, one to turn the shaft, one to actually watch the time and we normally set it once a week," said Jenkins.

Jenkins says while he won't quite be getting up at 2 AM to change the Colgate clock this Sunday, there are plans to take care of the clock for many years to come. Jenkins says they will be changing the clock first thing Monday morning.

"There were rumors that when Colgate closed they would take the clock down, it would be relocated, disassembled and that's all they were, rumors. The clock is not going anywhere. It’s been here since 1924 and hopefully it’s staying for another 100 years," said Jenkins.
