NAME

Time::Seconds - a simple API to convert seconds to other date values

SYNOPSIS

    use Time::Piece;
    use Time::Seconds;
    
    my $t = localtime;
    $t += ONE_DAY;
    
    my $t2 = localtime;
    my $s = $t - $t2;
    
    print "Difference is: ", $s->days, "\n";

DESCRIPTION

This module is part of the Time::Piece distribution. It allows the user to find out the number of minutes, hours, days, weeks or years in a given number of seconds. It is returned by Time::Piece when you delta two Time::Piece objects.

Time::Seconds also exports the following constants:

    ONE_DAY
    ONE_WEEK
    ONE_HOUR
    ONE_MINUTE
    ONE_MONTH
    ONE_YEAR
    ONE_FINANCIAL_MONTH
    LEAP_YEAR
    NON_LEAP_YEAR

Since perl does not (yet?) support constant objects, these constants are in seconds only, so you cannot, for example, do this: "print ONE_WEEK->minutes;"

METHODS

The following methods are available:

    my $val = Time::Seconds->new(SECONDS)
    $val->seconds;
    $val->minutes;
    $val->hours;
    $val->days;
    $val->weeks;
    $val->months;
    $val->financial_months; # 30 days
    $val->years;
    $val->pretty; # gives English representation of the delta

The usual arithmetic (+,-,+=,-=) is also available on the objects.

The methods make the assumption that there are 24 hours in a day, 7 days in a week, 365.24225 days in a year and 12 months in a year. (from The Calendar FAQ at http://www.tondering.dk/claus/calendar.html)

Bugs

Currently the methods aren't as efficient as they could be, for reasons of clarity. This is probably a bad idea.
