SYNOPSIS

my $upcoming = $r->upcoming();
# "2016-09-30T00:00:00Z" (depending on current time)
my $latest = $r->latest();
# ("2016-09-30T00:00:00Z", "2016-10-31T00:00:00Z", "2016-11-30T00:00:00Z",

DESCRIPTION
Convenient ways of handling recurrences.
CONSTRUCTORS
new
my $r = Time::R->new($start);
my $r = Time::R->new($start, end => $end, years => $year, months => $months,
weeks => $weeks, days => $days, hours => $hours, minutes => $minutes,
seconds => $seconds);
Creates a Time::R object starting at $start
, and optionally ending at $end
. Every argument except $start
is optional and can be in any order.
$start
-
This should be a Time::C object representing the starting time.
end => $end
-
This should be a Time::C object optionally specifying the ending time. Defaults to
undef
. years => $years
-
This should be the number of years between each recurrence. Defaults to
0
. months => $months
-
This should be the number of months between each recurrence. Defaults to
0
. weeks => $weeks
-
This should be the number of weeks between each recurrence. Defaults to
0
. days => $days
-
This should be the number of days between each recurrence. Defaults to
0
. hours => $hours
-
This should be the number of hours between each recurrence. Defaults to
0
. minutes => $minutes
-
This should be the number of minutes between each recurrence. Defaults to
0
. seconds => $seconds
-
This should be the number of seconds between each recurrence. Defaults to
0
.
ACCESSORS
start
my $start = $r->start;
$r->start = $start;
$r = $r->start($new_start);
Returns or sets the Time::C object representing the starting time of the recurrence. Setting this also calls $r->reset()
.
If the form $r->start($new_start)
is used, it likewise updates the start but returns the entire object.
current
my $current = $r->current;
$r->current = $current;
Returns or sets the Time::C object representing the current time of the current recurrence.
This may get changed by $r->next
, $r->upcoming
, $r->latest
, $r->until
, and $r->reset
.
end
my $end = $r->end;
$r->end = $end;
Returns or sets the Time::C object representing the end time of the recurrence.
years
my $years = $r->years;
$r->years = $years;
$r->years += 10;
$r->years++;
$r->years--;
Returns or sets the number of years between each recurrence. Setting this also calls $r->reset()
.
months
my $months = $r->months;
$r->months = $months;
$r->months += 12;
$r->months++;
$r->months--;
Returns or sets the number of months between each recurrence. Setting this also calls $r->reset()
.
weeks
my $weeks = $r->weeks;
$r->weeks = $weeks;
$r->weeks += 52;
$r->weeks++;
$r->weeks--;
Returns or sets the number of weeks between each recurrence. Setting this also calls $r->reset()
.
days
my $days = $r->days;
$r->days = $days;
$r->days += 7;
$r->days++;
$r->days--;
Returns or sets the number of days between each recurrence. Setting this also calls $r->reset()
.
hours
my $hours = $r->hours;
$r->hours = $hours;
$r->hours += 24;
$r->hours++;
$r->hours--;
Returns or sets the number of hours between each recurrence. Setting this also calls $r->reset()
.
minutes
my $minutes = $r->minutes;
$r->minutes = $minutes;
$r->minutes += 60;
$r->minutes++;
$r->minutes--;
Returns or sets the number of minutes between each recurrence. Setting this also calls $r->reset()
.
seconds
my $seconds = $r->seconds;
$r->seconds = $seconds;
$r->seconds += 60;
$r->seconds++;
$r->seconds--;
Returns or sets the number of seconds between each recurrence. Setting this also calls $r->reset()
.
METHODS
next
my $next = $r->next();
Sets $r->current
to and returns the next recurrence as a Time::C object. If the next time would happen after the $r->end
, it instead returns undef
and leaves $r->current
alone.
upcoming
my $upcoming = $r->upcoming();
Sets $r->current
to and returns the next time the recurrence occurs as a Time::C object based on the current time. If the next time would happen after the $r->end
, it instead returns undef
and leaves $r->current
alone.
latest
my $latest = $r->latest();
Sets $r->current
to and returns the latest time the recurrence occurs as a Time::C object based on the current time.
until
my @until = $r->until($end);
Returns all the recurrences that will happen from $r->current
until $end
(which should be a Time::C object), and updates $r->current
to the last one returned if any. If $r->end
is defined and $end
is after, it will instead use $r->end
as the limit.
reset
$r->reset();
Resets $r->current
to $r->start
.
