The data time zone: all data is stored using the Universal Time Zone (UTC)
The query time zone: this is the time zone of your Scuba instance. The default query time zone is either UTC or Pacific Standard Time (PST), but this can be configured to any time zone that you want to use.
Changing the query time zone simply shifts the events as they are displayed in Scuba, but doesn't change their original timestamps.
...
Relative time queries will be relative to the configured time zone. For example, "yesterday until today" will align to 12:00 AM XXX depending on the configured time zone. Queries using "1 day ago exactly until now" will be exactly 24 hours previous. See Time query syntax for more information.
How can I check which time zone I'm querying in?
Your time zone is displayed in the Explorer and in the New Cohort dialog next Explore page and preview panes within data model pages, next to the time fields.
