## Report Time Spent in Garbage Collection

### Description

This function reports the time spent in garbage collection so far in the R session while GC timing was enabled.

### Usage

    gc.time(on = TRUE)

### Arguments

`on` | logical; if `TRUE`, GC timing is enabled.

### Details

Due to timer resolution this may be under-estimate.

This is a primitive.

### Value

A numerical vector of length 5 giving the user CPU time, the system CPU time, the elapsed time and children's user and system CPU times (normally both zero), of time spent doing garbage collection whilst GC timing was enabled.

Times of child processes are not available on Windows and will always be given as `NA`.

### See Also

`gc`, `proc.time` for the timings for the session.

### Examples
