Constructive options for class 'Duration' — opts

These options will be used on objects of class 'Duration'.

Usage

opts_Duration(constructor = c("default", "dseconds", "duration", "next"), ...)

constructor: String. Name of the function used to construct the object, see Details section.
...: Additional options used by user defined constructors through the opts object

An object of class <constructive_options/constructive_options_Duration>

Depending on constructor, we construct the object as follows:

"default" (default): We build the object using the largest of lubridate::dyears(), lubridate::dmonths(), lubridate::dweeks(), lubridate::ddays(), lubridate::dhours(), lubridate::dminutes() and lubridate::dseconds() for which all the elements are whole numbers and the object is reproduced exactly, so an hour is built with lubridate::dhours(1) rather than lubridate::dseconds(3600). Note that the years and months of 'lubridate' durations are fixed approximations, of 365.25 and 30.4375 days respectively, so 31557600 seconds come out as lubridate::dyears(1). NA elements don't constrain the choice, and we use lubridate::dseconds() if all elements are NA or zero, or if the object is empty.
"dseconds" : We build the object using lubridate::dseconds() on a number of seconds.
"duration" : We build the object using lubridate::duration() on a number of seconds.
"next" : Use the constructor for the next supported class.
