Very useful indeed.... I spent way too long looking for this setting with a user. I know that HubSpot is focused on smaller businesses, but users being able to set their own timezones is pretty critical to a lot of organizations.
We need this feature too. With a sales team in several different timezones, we need the overall company Hubspot to remain in the timezone of our HQ location - but need our individual users to be able to change their timezone so that sync and integrations work better into Gcal for booking sales meetings etc
Please add Hubspot as keeping all users tied to the timezone of where the Hubspot account was established seems a little basic.
