haha, that's more than 64 bits even if we allow those past dates to have negative numbers they will only give us until like 1630 or something

UNIX timestamp for Plato's Republic, assuming 01 January 392 B. C. at 12:00 am is -19374092131393201937362373274. 🤣
over 19 digits is more than 64 bits
but, interesting point, the value is a JSON integer, i don't think it allows over 64 bit unsigned anyhow
bigger numbers are generally treated using generalised "big integer" math that uses byte arrays and arbitrary lengths, and to encode them in JSON you will usually then need to put them in a string, that's also why they are strings for npubs and event ids
also, -382-01-01T12:00 is shorter
