  * **timezone** (*Optional* *\[*[*str*](https://docs.python.org/3/library/stdtypes.html#str) *]*) -- Timezone of the interval.
  * **start\_time** (*Optional* \*\[\**Union* \*\[\**datetime* *,* *date* *,* [*str*](https://docs.python.org/3/library/stdtypes.html#str) *]* *]*) -- Start time of the interval.
