# Timestamp ### Overview The Timestamp pallet allows the validators to set and validate a timestamp with each block. It uses **`inherents`** for timestamp data, which is provided by the block author and validated/verified by other validators. The timestamp can be set only once per block and must be set each block. There could be a constraint on how much time must pass before setting the new timestamp. ### Dispatchable Calls * **`set`** - sets the current time. When setting the new time, it must be greater than the last one (set into storage) with at least a MinimumPeriod ### Configuration Timestamp requires to set following constants during the runtime initialisation: * **`minimumPeriod`** - minimum period between timestamps. Also, minimal interval between two blocks. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
