On a practical note, we don’t tend to prefix zeroes to numbers because they are superfluous. If programmers are using strings to store a year and those strings are limited to four digits, your project likely has a host of other issues that will become problems long before Y10K.
We already have a precedent, in programming, for prefixed zeroes having meaning: “an octal number follows.” Much like 0x indicates a hexadecimal number.
What's the point of prefixing 0 to dates written forum posts? It just confuses contemporary human readers.
Historians do a reasonable job at adequately translating dates from thousands of years ago across multiple calendar changes and societal collapses. Whatever future historian 10k+ years in the future is reading your post, should it survive, will be able to work out the date in the post, just from the language and other context clues alone.
It'll be hard to confuse 12025 with 2025 in the same way it's hard to confuse 2025 with AD 25.
