--[=====[
    Some things like weather and stock quotes will have an "interval" filed. This
    allows you to check things on a periodic basis and avoid getting rate-limited
    when using APIs.

    The format of the interval filed is <number><unit>, e.g., 15m for 15 minutes.
    Valid units are (s)econd, (m)inute, (h)our, and (d)ay. An invalid entry will
    result in the default of 15m. In other words, if you change an interval to
    "10z", the function to determine the number and multiplier will not be able to
    recognize the input and will default to 15 minutes.
