+# Timestamp Module
+
+The Timestamp module provides functionality to get and set the on-chain time.
+
+- [`timestamp::Trait`](./trait.Trait.html)
+- [`Call`](./enum.Call.html)
+- [`Module`](./struct.Module.html)
+
+## Overview
+
+The Timestamp module 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.
+
+**NOTE:** The Timestamp module is the recommended way to query the on-chain time instead of using
+an approach based on block numbers. The block number based time measurement can cause issues
+because of cumulative calculation errors and hence should be avoided.
+
+## Interface
+
+### Dispatchable Functions
+
+* `set` - Sets the current time.
+
+### Public functions
+
+* `get` - Gets the current time for the current block. If this function is called prior to
+setting the timestamp, it will return the timestamp of the previous block.
+
+### Trait Getters
+
+* `MinimumPeriod` - Gets the minimum (and advised) period between blocks for the chain.
+
+## Usage
+
+The following example shows how to use the Timestamp module in your custom module to query the current timestamp.
+
+### Prerequisites
+
+Import the Timestamp module into your custom module and derive the module configuration
+trait from the timestamp trait.
+
+### Get current timestamp
+
+```rust
+use frame_support::{decl_module, dispatch};
+use frame_system::ensure_signed;
+
+pub trait Trait: timestamp::Trait {}
+
+decl_module! {
+	pub struct Module<T: Trait> for enum Call where origin: T::Origin {
+		#[weight = 0]
+		pub fn get_time(origin) -> dispatch::DispatchResult {
+			let _sender = ensure_signed(origin)?;
+			let _now = <timestamp::Module<T>>::get();
+			Ok(())
+		}
+	}
+}
+```
+
+### Example from the FRAME
+
+The [Session module](https://github.com/paritytech/substrate/blob/master/frame/session/src/lib.rs) uses
+the Timestamp module for session management.
