KV expiration & TTLs can only be 32-bit signed integers in practice

[huw]

Ran into this because I accidentally sent epoch milliseconds as expiration in KV. This also happens for expirationTtl.

Reproduction

kvNamespace.put(“key”, “value”, { expiration: 1675058732043 })

Expected behaviour

In the Workers environment, this throws a TypeError:

TypeError: Value out of range. Must be between -2147483648 and 2147483647 (inclusive).

Actual behaviour

The put succeeds
