GitLab Team Calls - Timezone Agnostic
Overview
Use moment.js to display the GitLab team call in PST/UTC and the local users timezone. This adds more weight to the main handbook page as it's loading both moment.js and moment-tz.js libraries. Both calls are configured using PST as the "base" time.
This fixes some concerns raised in https://dev.gitlab.org/gitlab/organization/issues/976
