execute_chore is formatting time in UTC time. grocy server ignores the timezone, so it shifts the date of chore execution about pygrocy HOT 3 CLOSED

Actually this might be doing the reverse of #51

I'm confused if it's not possible to fix this in a general way. It seems to me like grocy is not handling track_date_only chores correctly, but they claim it is not an issue.

Looks like maybe needs to be fixed here: hassio-addons/addon-grocy#274

Just to note it also here what's the current state (since ever) about date-times in grocy to avoid confusion:

No timezone information is handled anywhere currently, so any date-time, on any API endpoint, needs to be provided without timezone information (or it would be ignored anyways).

So to make time related things work, all parts involved need to be in the same timezone - there are 3 settings:

• The client (client side frontend JS uses that)
• The OS setting of the server (SQLite uses that)
• The php.ini setting date.timezone (PHP uses that)

This should be easily achievable in self hosted setups, when not already the case.

Timezone support in general is already tracked in grocy/grocy#214.

There is also the API endpoint /system/time which returns server-side time information:

time_local, time_local_sqlite3 and the local client time need to match.
