@plsburydoughboy the talk at the moment is what can be called the year 2038 problem
It's a potential issue in how computers store dates and times at a low level, because computers it's possible that when the clock hits 03:14:08 on Tuesday, 19 January 2038 software might misinterpret it as being some time in 1901
Also the reason there weren't any issues in 2000 was the sheer amount of remediation work done, not that it wasn't a problem
