// 2017-05-24T08:58:42.857401+00:00 app[web.1] level=info message="Server is starting"
error(new Error('I am an error '))

Sometimes you don't want those logs e.g. when testing things, in this case you can pass a env variable in the command line and the module is muted
$ HEROKU_LOG=disable mocha test.js
If the environment is not production heroku-log will add a simple time-mark at the beginning of each log, in production it will be hidden since Heroku adds a time block by itself.
