There was a 2011 sci fi movie kinda about that. The movie wasn't that good but it had some interesting ideas:

In 2169, people are genetically engineered to stop aging on their 25th birthday, when a one-year countdown on their forearm begins. When it reaches zero, the person "times out" and dies instantly. Time has thus become the universal fiat currency, transferred directly between people or stored on flashdrive type devices, some in secure bank vaults. Distinct socioeconomic caste "Time Zones" exist; Dayton is the poorest, a manufacturing hub and "ghetto" where people rarely have over 24 hours on their clocks, whereas in New Greenwich, the affluent Zone of plutocrats, people have enough time to be essentially immortal. ... the people of New Greenwich hoard most of the time, while constantly increasing prices to impoverish people in less prosperous districts.
