+title: Accessing Time in Sui Move

 You have options when needing to access network-based time for your transactions. If you need a near real-time measurement (within a few seconds), use the immutable reference of time provided by the `Clock` module in Sui Move. The reference value from this module updates with every network checkpoint. If you don't need as current a time slice, use the `epoch_timestamp_ms` function to capture the precise moment the current epoch started.

 Successive calls to `sui::clock::timestamp_ms` in the same transaction always produce the same result (transactions are considered to take effect instantly), but timestamps from `Clock` are otherwise monotonic across transactions that touch the same shared objects:  Successive transactions seeing a greater or equal timestamp to their predecessors.
