Time::Duration::Parse(3pm)				User Contributed Perl Documentation				Time::Duration::Parse(3pm)

NAME
Time::Duration::Parse - Parse string that represents time duration SYNOPSIS
use Time::Duration::Parse; my $seconds = parse_duration("2 minutes and 3 seconds"); # 123 DESCRIPTION
Time::Duration::Parse is a module to parse human readable duration strings like 2 minutes and 3 seconds to seconds. It does the opposite of duration_exact function in Time::Duration and is roundtrip safe. So, the following is always true. use Time::Duration::Parse; use Time::Duration; my $seconds = int rand 100000; is( parse_duration(duration_exact($seconds)), $seconds ); FUNCTIONS
parse_duration $seconds = parse_duration($string); Parses duration string and returns seconds. When it encounters an error in a given string, it dies an exception saying "Unknown timespec: blah blah blah". This function is exported by default. AUTHOR
