Truffle: Feature Request: add time property to truffle-config.js

[pieterhartel]

Issue

Ganache-core and ganache-cli have options to set a specific time stamp on the genesis block, but there is no way to specify this in a truffle-config.js

Expected Behavior

Adding a genesis_time property as suggested below would enable truffle test to start the default ganache-core with the appropriate time.

module.exports = {
 ...
      genesis_time: "2019-04-09T02:10:14Z"
 ...
};

Thanks for the suggestion @pieterhartel, we'll look into what this might entail!

Requirements

1. Enable the usage of a genesis_time property in a given truffle-config.js.

Example:

module.exports = {
  networks: {
    development: {
      host: "127.0.0.1",
      port: 8545,
      genesis_time: "2019-04-09T02:10:14Z",
      network_id: "*"
    }
  }
};

1. Throw a helpful Error if genesis_time is not passed a valid Date.
2. Ensure that the valid genesis_time value is passed as a configurable option internally within truffle before starting a default ganache-core chain for truffle test.
3. Add an integration mocha test to proper functionality (proper behavior when passed a valid Date and proper error handling when passed an invalid Date).

Prerequisite Context

• Familiarity with the options ganache-core is expecting on its side for setting a genesis block time: https://github.com/trufflesuite/ganache-core#options
• Familiarity with the entry point for truffle test: https://github.com/trufflesuite/truffle/blob/develop/packages/truffle-core/lib/commands/test.js, specifically these lines.
• Familiarity with the script for spinning up the default ganache-core in testing: https://github.com/trufflesuite/truffle/blob/develop/packages/truffle-environment/chain.js
• Possibly familiarity with the chain environment file for error handling (might be better handled earlier in the truffle test sequence): https://github.com/trufflesuite/truffle/blob/develop/packages/truffle-environment/environment.js
• Familiarity with current truffle test integration tests, i.e. https://github.com/trufflesuite/truffle/blob/develop/packages/truffle/test/scenarios/happy_path/happypath.js, particularly these lines.
