BNB Chain announced that BEP-706 will be included in the Jenner hard fork, adding a precompiled contract at address 0x70 to provide smart contracts with millisecond-level block timestamps. According to Odaily, the new interface will let developers read timestamps in milliseconds, while the existing `block.timestamp` value and second-based timing logic will remain unchanged.
The feature is intended for applications requiring subsecond precision, including quote settlement with validity periods of several hundred milliseconds, auction deadlines and checks on price oracle data freshness. The precompiled contract will cost 20 gas, with additional costs for the call and memory. BNB Chain advised developers to check unit consistency between seconds and milliseconds and verify that calls succeed and return the expected 32 bytes of data.
