 * *Cheaper data availability:* Starknet uses link:https://eips.ethereum.org/EIPS/eip-4844[EIP-4844].
 * Time-related syscalls when called from an account contract's `+__validate__+` function:
-** `timestamp` returns the hour, rounded down.
+** `block_timestamp` returns the hour, rounded down.
 ** `block_number` returns the block number, rounded down to the nearest multiple of 100.
 * *Optimization:* Load into memory only the functions in a contract that are actually used when generating the proof.
