The options chains fetcher counted days to expiration from the machine's local calendar date, so one contract got a different DTE depending on where the machine was: five hours before it expires, a machine in America/Los_Angeles got 1 day where UTC and Tokyo got 0. It also disagreed with the provider's own analysis chain, which counts to the 08:00 UTC instant the exchange expires the contract at. Both now go through one helper, days_to_expiration(), which counts the whole days left to the expiration timestamp Deribit publishes. A contract listed without one falls back to 08:00 UTC on the date in its name. time-machine joins the dev group to freeze the clock and the local timezone in the tests.

Providers
In this folder you can find the providers that were created or are supported by OpenBB.
Recommended structure
Every provider is located within a directory, with the following structure:
openbb_platform
└───providers
└───<provider_name>
| README.md
│ pyproject.toml
│ uv.lock
|───tests
└───openbb_<provider_name>
│ __init__.py
|───models
| |───<some model>.py
| └───...
└───utils
|───<some helper>.py
└───...
The models define the data structures that are used to query the provider endpoints and store the response data.
