Every user is able to change the timezone to their liking.
Where is the Timezone Used
A set timezone is used for all dates in the system, reports and tables.
The only exception is the date in the open balance menu, it is always in the system timezone. This is done in order for all settlements to use the same hour range.
How to Change the User Timezone
The user timezone is changed from the user menu at the top. Click the time that is present in the user menu, then use the cogwheel to get to the settings, and select a new timezone.
Keep in mind that if you change the user timezone, the current page is reloaded and records might move out of the current view, as they might be present on a different day in the newly selected timezone.
