monitor_timeRange

This function is a wrapper for <code>range(monitor$data$datetime)</code>
and is convenient for use in data pipelines.
Dates will be returned in the timezone associated with
<code>monitor$data$datetime</code> which is typically "UTC" unless
<code>timezone</code> is specified.

Utilities for working with hourly air quality monitoring data
with a focus on small particulates (PM2.5). A compact data model is
structured as a list with two dataframes. A 'meta' dataframe contains
spatial and measuring device metadata associated with deployments at known
locations. A 'data' dataframe contains a 'datetime' column followed by
columns of measurements associated with each "device-deployment".
Algorithms to calculate NowCast and the associated Air Quality Index (AQI)
are defined at the US Environmental Projection Agency AirNow program:
