.SH "NAME"
Time::Duration::Parse \- Parse string that represents time duration
.SH "SYNOPSIS"

.Vb 1
\&  use Time::Duration::Parse;

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Time::Duration::Parse is a module to parse human readable duration
strings like \fI2 minutes and 3 seconds\fR to seconds.
.PP
It does the opposite of \*(L"duration_exact\*(R" in Time::Duration function
in Time::Duration
and is roundtrip safe.
So, the following is always true.
.PP
.Vb 2
\&  use Time::Duration::Parse;
\&  use Time::Duration;
\&
\&  my $seconds = int rand 100000;
\&  is( parse_duration(duration_exact($seconds)), $seconds );
.Ve
.SH "FUNCTIONS"
.IX Header "FUNCTIONS"
.IP "parse_duration" 4
.IX Item "parse_duration"
.Vb 1
\&  $seconds = parse_duration($string);
.Ve
.Sp
Parses duration string and returns seconds.
When it encounters an error in a given string,
it dies with an exception saying \*(L"Unknown timespec: blah blah blah\*(R".
This function is exported by default.
.SH "SEE ALSO"
.IX Header "SEE ALSO"
Time::Duration::Parse::More has the same interface as this module,
but supports more expressions and memoization.
.PP
Time::Duration can be used for the reverse of this module:
given a number of seconds it will provide an English description of
the duration.
.PP
Time::Duration::Object provides an \s-1OO\s0 interface to Time::Duration.
.PP
Time::Duration::LocaleObject provides an \s-1OO\s0 interface to the
\&\f(CW\*(C`Time::Duration::??\*(C'\fR modules, which provide language-specific versions
of Time::Duration.
.PP
DateTime::Format::Duration can be used to parse natural language
descriptions of durations, returning an instance of DateTime::Duration,
which can then be converted to seconds using the \f(CW\*(C`in_units()\*(C'\fR method.
