Timezone
All times are stored in the database in UTC +0. In Prisma, DateTime is mapped to timestamp(3) by default for a PostgreSQL database. DateTime is in ISO8601 format. Package used is date-fns-tz in the frontend. See #input/dropdownTimezone for more information.
YYYY-MM-DDTHH:mm:ss.sssZ
The timezone is always UTC (as denoted by suffix z)
using the voyage schedule as an example,
Note
Jim’s time is CDT, GMT-5 during daylight saving, and GMT-6 otherwise
For Voyage 50,
- Voyage Launch will be July 1 noon (12:00) Jim’s time
- Sprints end at 11:59pm (23:59) Sundays Jim’s time (so they would start 00:00 Mondays Jim’s time)
- Sprint check-in will due at the same time as each sprint ends (23:59 sundays Jim’s time)
- Voyage end and project due would be the same as Sprint 6 end (23:59 sundays Jim’s time)
- For solo project, completion certificates, and voyage showcase dates, exact times do not matter, so we will set it to 23:59 PST/PDT
