Include the desired time range in your pinned query as in these examples:
- office 1am to 5am
- people in warehouse 8:30pm to 4:15am
- garage entrance 1am PST to 5am PST
Whenever your pinned query includes a time range, the alert is sent only when the triggering event falls within that time range.
NOTE: Currently, the interpretation of the time range is determined at the time you pin your query. So be careful with daylight savings time if you don't specify the timezone as part of your pinned query.
