Time Zones and Date in Database

Hi there. I’ve been trying to figure out how bubble.is works with time zones. I can see that the date can be formatted to show the time zone. After shooting a timestamp in from Zapier, how does it get stored? And how does it display to the current user? Would it show in their current time zone or in the time zone of the database/ app?

Also, if it does detect location, does it do this through ip address?

Thanks.
