timegm() in Time::Local == gmtime() in POSIX

After looking it looks like Time::Local is a Pure Perl interface to the Perl localtime objects where POSIX is an XS interface to the system libraries.

Not at all. Look at the arguments...

Function POSIX equivalent Purpose of Function
CORE::gmtime POSIX::gmtime Returns GMT time components from epoch time.
Time::Local::timegm [none] Returns the epoch time from GMT time components.
CORE::localtime POSIX::localtime Returns local time components from epoch time.
Time::Local::timelocal POSIX::mktime Returns the epoch time from local time components.

POSIX is missing the very function that's needed here.

I'm not sure that's quite right...

sub gmtime {
    usage "gmtime(time)" if @_ != 1;
    CORE::gmtime($_[0]);
}
