To load all entities in this group load the `dates_loader.lgt` utility 
file:

	| ?- logtalk_load(library(dates_loader)).

The `date` object implements some useful calendar date predicates.

The `time` object implements some useful time predicates.

Please note that some of the functionality of these objects depends 
on the chosen Prolog support for accessing operating system time and 
date data.
