Every manager can be configured with optional time ranges. Time ranges are used to override the manager's minimum/maximum dyno quantity during certain times of any day of the week.
Time ranges operate in the time zone of the organization. Newly created organizations default to the UTC time zone. You may update the time zone of the organization on the organization page (Sidebar > Organizations > Your Organization > Edit).
You can have multiple time ranges. You can reorder them from the HireFire UI and it'll try the match the current time conditions in order from top to bottom. The first time range that matches will be used for the duration of the minutely checkup operation.
When using multiple time ranges for a single manager, their matching conditions are allowed to (partially or fully) overlap.
