setWhenMeasured(x, when.measured, ...)

## 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"), ...)

Arguments

x

a generic_spct object

when.measured

POSIXct to add as attribute, or a list of POSIXct.

...

Allows use of additional arguments in methods for other classes.

Value

x

Methods (by class)

Note

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).
