%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 where possible.
