When displaying a timestamp that includes a time, include the time in ET (TICKET: Add a transformer Date → string with ET at the end, for view only)and append “ET” or “Eastern” after it. Don’t think there are examples of this currently, but if added you should make a new pipe for it.
Back-End
Endpoints dealing with timestamps should send as yyyy-mm-ddThh:mm:ss.sssZ or similar. Axios and Express so this automatically with JS Date objects. (TODO: see if frontend and backend timestamps are sent in exactly the same format)
Endpoints dealing with dates only should send yyyy-mm-dd only to avoid confusion.
