=head1 NAME
Benchmark::Dumb::SimpleTime - Benchmark::Dumb interface for simple time() based benchmarking
=head1 VERSION
This document describes version 1.063 of Benchmark::Dumb::SimpleTime (from Perl distribution Bencher-Backend), released on 2023-07-08.
=head1 DESCRIPTION
Used internally by L<Bencher::Backend>.
This benchmarks code using simple C<time()> to measure time interval. No
outliers removal or any statistics methods are applied. Returns result similar
to what L<Benchmark::Dumb>'s C<_timethese_guts()> returns, with C<errors> set to
C<[undef]>. Might be usable if you don't care about any of the stuffs that
L<Dumbbench> cares about, and you want to benchmark code that runs at least one
or a few seconds with few iterations (1 to 5) , where Benchmark::Dumb will
complain that the "number of runs is very small".
=head1 HOMEPAGE

=head1 CONTRIBUTING
To contribute, you can send patches by email/via RT, or send pull requests on
GitHub.
Most of the time, you don't need to build the distribution yourself. You can
simply modify the code, then test via:
% prove -l
If you want to build the distribution (e.g. to try to install it locally on your
system), you can install L<Dist::Zilla>,
L<Dist::Zilla::PluginBundle::Author::PERLANCAR>,
L<Pod::Weaver::PluginBundle::Author::PERLANCAR>, and sometimes one or two other
Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond
that are considered a bug and can be reported to me.
