The motivation of this is to have api.tx.timestamp.set function
from Polkadot.js available for use in integration tests.
The problem is that set() function in timestamp pallet
only allows calls with inherent origin because of mandatory
dispatch.
The structure of the project is a mix of ink! and TypeScript.
Please see redspot.config.ts for Redspot configuration.
The integration tests are located in the tests directory.
The artifacts folder contains the contract artifacts.
