Review Comment:
> if we could quickly identify that the string has a period/end
configuration, we could parse both parts separately.
Regarding this, I have this solution in mind:
1. Suppose start is a timestamp, end is a period string.
2. Parse the period string to a long.
3. `endMillis` = period in long + `startMillis`
This method does not work all the time though. We may not get the correct
number for leap years, or even months. We will need to calculate start/end
period with awareness of these semantics, which is more complex. I feel we can
stick with knowing that we are dealing with the most common data format
(`"YYYY-MM-DD'T'HH:mm:ss.SSSZ/YYYY-MM-DD'T'HH:mm:ss.SSSZ"`) for this method,
and use `Interval.of(String)` for other formats?
