=over

=item time

Returns the number of non-leap seconds since whatever time the system
considers to be the epoch (that's 00:00:00, January 1, 1904 for Mac OS,
and 00:00:00 UTC, January 1, 1970 for most other systems).
Suitable for feeding to C<gmtime> and C<localtime>.

For measuring time in better granularity than one second,
you may use either the Time::HiRes module (from CPAN, and starting from
Perl 5.8 part of the standard distribution), or if you have
gettimeofday(2), you may be able to use the C<syscall> interface of Perl.
See L<perlfaq8> for details.
