If no time data is available from in slot
runtime.all and argument
the sequential time as computed by
is returned, and a warning is thrown unless
`runtime.all`(object, null = FALSE, warning = TRUE)
- a logical that indicates if the sequential
time should be returned if no time data is available in
- a logical that indicates if a warning
should be thrown if the sequential time is returned
instead of the real CPU time.
- an object computed using some algorithm, or
that describes an algorithm itself.
