datetime

This function calculated the local date-time for an observation based on a
date-time in Coordinated Universal Time (UTC). The function provides a
wrapper for the <code>with_tz</code> function form the <code>lubridate</code> package.
It converts output from the <code>with_tz</code> function to a character vector
so other functions in this package can be applied without error to
with a dataframe with observations from multiple time zones to local time.


Inputs date-times in Coordinated Universal Time (UTC)
and converts to a local date-time and local date for US counties, based on
each county's Federal Information Processing Standard (FIPS) code.
