OMG, I’m dealing with a developer right now that is dealing with patient collected samples in several timezones, allowing the patients to either enter the time they collected, or use current time, and storing it in UTC time.

We do not receive any timezone data, patient collection data is showing different days than the patient could write on their samples depending on the time of day, and the developer said ‘just subtract X hours’ (our timezone)… for which not all patients would live in.

I suppose I could, if they’d provide the patient’s timezone, but they don’t even collect that. Can you just admit your solution is bad? It’s fine to store a timestamp in UTC, but not user provided data… don’t expect average users to calculate their time (and date) in UTC please.
