Daylight savings.
It's a debate that divides the nation, both figuratively and in terms of when they get to watch the footy.
And now the debate has been ignited once more by a lone politician pushing to introduce daylight savings in Western Australia.
The southern states put their clocks forward an hour on the first Sunday of October each year, and back an hour on the first Sunday in April, meaning that WA is three hours behind the east during the summer and two hour behind during the winter.
Daylight Savings Party leader Wilson Tucker has drafted a bill that would align WA with NSW, Victoria, South Australia, Tasmania, the ACT and Norfolk Island during the summer months.
But the bill is likely to face heavy opposition in the state parliament as Western Australians have rejected daylight savings in four referendums in 1975, 1984, 1992 and 2009.
Mr Tucker said introducing daylight savings in WA would help overcome some of the communication issues with the eastern states.

"Time zones are playing a more prominent role in how we how we communicate and how we how we do business out in the West," he said.
"We are beholden in a big way to the East Coast time zone and a three-hour differences is quite significant in those summer months. So reducing that time is certainly becoming more and more important these days."
The MP for the the Mining and Pastoral region also said daylight savings would give people more time to spend with their family and friends after work.
"We live in this fantastic, laidback state, and it's really about allowing giving more time in the afternoons to maximise recreational time. Work life balance is incredibly important," he said.

Mr Tucker plans to give notice of his Daylight Saving Bill 2022 in the WA Parliament this week for debate next year and has invited the public to look at his Bill and provide feedback in the meantime.
"I'm not trying to just shove this down people's throats, to put it bluntly. I do want to hear feedback from people. I am firmly in the belief that we do have majority support for the issue and therefore a mandate for it," he said.
He believes there is widespread support for his cause by extrapolating data from the previous referendum and travelling around WA and speaking to constituents as well as other state MPs.
The only other states and territories that do not observe daylight savings are Queensland and the Northern Territory due to their tropical climates.
