Implicit indirect dependency in test.t

[kentfredric]

I struck some anomaly today in this, and I was looking at this line in test.t wondering how it worked:

Email-Date/t/test.t

Lines 8 to 10 in f197839

	my $time = time;
	my $date = Time::Local::timelocal Date::Parse::strptime format_date($time);
	cmp_ok($date, '==', $time, 'format_date output was parsed back into input');

Given there is no use Time::Local anywhere in Email-Date.

A bit of digging and it turns out you're relying on Date::Parse to load it for you:
https://metacpan.org/release/TimeDate/source/lib/Date/Parse.pm#L10

So although it currently works, this dependency might be fragile as is without a proper use declaration, and probably an explicit TEST_REQUIRES dep. ( And it makes for better metadata either way for sec/audit/tooling reasons )
