Times, perhaps. But dates should never be stored with a timezone at all, except in extremely rare cases where a day for some reason specific to a timezone. But even then, it's much more likely that you are trying to specify a time range that happens to start and end on a certain day in a certain place. Dates, almost by definition, are independent of timezone. January 1st, 2020 began at several different times in different timezones. It should be represented as a date stamp: 2020-01-01 without any timezone. If you really are trying to represent the day that starts at 12:00 AM PST on January 1, 2020 and ends at 12:00 PM PST the same day, then you probably just want two timestamps representing those instants and not a date at all. But again, that would be quite rare. In most cases you would just want to store 2020-01-01.
