Sauce Labs servers run UTC. While this is good general practice, for tests with time-sensitive database fixtures or requirements, the developers' time zone may be preferable.

Add a time-zone key to the capabilities object in your Protractor config file. Bear in mind that this is overriden by any multiCapabilities object you may have - if it exists, add them to that object instead.

Possible time-zone values are on Wikipedia - bear in mind only the latter portion is used (i.e. London, Samoa, Havana)

Using Protractor's example config file as a base:

exports.config = {
  // get auth tokens from parent environment
  // i.e. if BASH: export SAUCE_USERNAME=Andy
  sauceUser: process.env.SAUCE_USERNAME,
  sauceKey: process.env.SAUCE_ACCESS_KEY,

  // Capabilities to be passed to the webdriver instance
  // - webdriver config can be extended with Sauce Labs's 
  // custom conf options from 
  capabilities: {
    'browserName': 'chrome',
    'time-zone': 'London'

  // Spec patterns are relative to the current working directly when
  // protractor is called.
  specs: ['example_spec.js'],
