Set the "when.measured" attribute
Function to set by reference the "when" attribute of an existing generic_spct or an object of a class derived from generic_spct.
setWhenMeasured(x, when.measured, ...) when_measured(x) <- value ## Default S3 method: setWhenMeasured(x, when.measured, ...) ## S3 method for class 'generic_spct' setWhenMeasured(x, when.measured = lubridate::now(tzone = "UTC"), ...) ## S3 method for class 'summary_generic_spct' setWhenMeasured(x, when.measured = lubridate::now(tzone = "UTC"), ...) ## S3 method for class 'generic_mspct' setWhenMeasured(x, when.measured = lubridate::now(tzone = "UTC"), ...)

generic_spct: generic_spct
summary_generic_spct: summary_generic_spct
generic_mspct: generic_mspct
This method alters x itself by reference and in addition
returns x invisibly. If x is not a generic_spct or an object of a class derived from
generic_spct, x is not modified. If when is not a POSIXct object
or NULL an error is triggered. A POSIXct describes an
instant in time (date plus time-of-day plus time zone).
