BSC Jenner Hard Fork Adds Millisecond Timestamps for Smart Contracts

BNB Chain has included BEP-706 in its Jenner hard fork, adding a precompiled contract at address 0x70 that lets smart contracts read current block timestamps in milliseconds. According to Odaily, the proposal lets developers retrieve elapsed milliseconds since the Unix epoch; previously, contracts could access only second-level timestamps through block.timestamp, making it impossible to distinguish blocks produced within the same second. The feature can improve precision for time-limited signature quotes, auction deadlines, and checks on price-oracle update timeliness. It is an incremental upgrade and does not change the existing second-level return behavior of block.timestamp.
