NAME
Test::Recent - check a time is recent
SYNOPSIS
use Test::More;
use Test::Recent qw(recent);
# check things happened in the last ten seconds
recent DateTime->now, "now is recent!";
recent "2012-12-23 00:00:00", "end of mayan calendar happened recently?";
# check things happened in the last hour
recent "2012-12-23 00:00:00", DateTime::Duration->new( hours => 1 ), "mayan";
recent "2012-12-23 00:00:00", "1 hour", "mayan"DESCRIPTION
Simple module to check things happened recently.
Functions
These are exported on demand or may be called fully qualified
- recent $date_and_time
- recent $date_and_time, $test_description
- recent $date_and_time, $duration, $test_description
-
Tests (using the Test::Builder framework) if the time occurred within the duration ago from the current time. If no duration is passed, ten seconds is assumed.
- occured_within_ago $date_and_time, $duration
-
Returns true if and only if the time occurred within the duration ago from the current time.
Parsing of DateTimes
This module supports the following things being passed in as a date and time:
- A DateTime object
- An ISO8601 formatted date string
-
i.e. anything that DateTime::Format::ISO8601 can parse
- A Postgres style TIMESTAMP WITH TIME ZONE
-
i.e. something of the form
YYYY-MM-DD HH:MM:SS.ssssss+TZ
Older versions of this module used DateTimeX::Easy to parse the datetime, but this proved to be unreliable.

BUGS
This module ignores sub-seconds. This is primarily because the current implementation of DateTime's now method does not return nanoseconds, meaning that technically now returns a time that is in the past and might occur before a timestamp you hand in that contained nanoseconds (and therefore would erroneously be not concidered "recent")

In order not to depend on another DateTime library, this module converts postgres style TIMESTAMP WITH TIME ZONE by using a regular expression and simply ignoring microseconds. This potentially introduces a one second inaccuracy in the recent handling.
