[Rd] print.POSIXct doesn't seem to use tz argument, as per its example

On the documentation page for DateTimeClasses, in the Examples section,
there are the following two lines:
format(.leap.seconds) # the leap seconds in your time zone
print(.leap.seconds, tz = "PST8PDT") # and in Seattle's
The second line (using print) seems to ignore the tz argument, and prints
the dates in my time zone, while:
format(.leap.seconds, tz = "PST8PDT")
does print the dates in PST. The code in
https://github.com/wch/r-source/blob/trunk/src/library/base/R/datetime.R
around line 234 looks like the ... argument is passed to print, not to
format.
print.POSIXct <-
print.POSIXlt <- function(x, ...)
{
max.print <- getOption("max.print", 9999L)
if(max.print < length(x)) {
print(format(x[seq_len(max.print)], usetz = TRUE), ...)
cat(' [ reached getOption("max.print") -- omitted',
length(x) - max.print, 'entries ]\n')
} else print(if(length(x)) format(x, usetz = TRUE)
else paste(class(x)[1L], "of length 0"), ...)
invisible(x)
}
The documentation for print() on this page seems to be silent on tz as an
argument, but I do believe the example using print() does not work as
advertised.
Thanks.
