Prisma DateTime handling and PostgreSQL TIMESTAMPTZ synchronization

Prisma enforces UTC storage for all DateTime values across supported database providers. When utilizing PostgreSQL, the TIMESTAMPTZ type is used to ensure data is stored in UTC, but the Prisma Client returns these as standard JavaScript Date objects.

Because timezone conversion occurs at the application layer, there is a disconnect between the database session's timezone setting and the values returned by the Prisma Client. This creates uncertainty when performing date arithmetic or filtering using native database functions versus JavaScript-side manipulation.

Does the Prisma Client provide a mechanism to respect database-level session timezone offsets during serialization?
How can consistency be guaranteed when mixing native SQL date functions with Prisma's UTC-enforced DateTime objects?

How does PostgreSQL's AT TIME ZONE handle daylight saving transitions when converting UTC timestamps to a regional time zone on DigitalOcean Managed Databases?
You need to persist event timestamps in UTC and later present them in a user‑specific regional time zone, accounting for daylight‑saving shifts.
How can I reliably convert request timestamps to a specific regional time zone in a Fiber handler?
In a Fiber application, I need to parse incoming ISO‑8601 timestamps from JSON payloads, interpret them as UTC, then convert to a user‑specified regional time zone (e.g., America/New_York) for storage or display.
