Description: A Shiny Input for date-ranges, which pops up two calendars for selecting dates, times, or predefined ranges like "Last 30 Days". It wraps the JavaScript library 'daterangepicker' which is available at <https://www.daterangepicker.com>.

Title: Nominal Dates, Times, and Durations
Description: Provides methods for working with nominal dates, times, and
durations. Base R has sophisticated facilities for handling time, but these
can give unexpected results if, for example, timezone is not handled properly.
This package provides a more casual approach to support cases which
do not require rigorous treatment.  It systematically deconstructs the
concepts origin and timezone, and de-emphasizes the display of seconds. It
also converts among nominal durations such as seconds, hours, days, and weeks.
See '?datetime' and '?duration' for examples. Adapted from 'metrumrg'

Description: Utilities for handling dates and times, such
as selecting particular days of the week or month,
formatting timestamps as required by RSS feeds, or
converting timestamp representations of other software
(such as 'MATLAB' and 'Excel') to R. The package is
lightweight (no dependencies, pure R implementations) and
relies only on R's standard classes to represent dates
and times ('Date' and 'POSIXt'); it aims to provide
efficient implementations, through vectorisation and the
use of R's native numeric representations of timestamps
