Passing DateTime as startDay including microseconds will set first recurrence to the next day instead of current

[deadpony]

$transformer = new \Recurr\Transformer\ArrayTransformer();

$transformerConfig = new \Recurr\Transformer\ArrayTransformerConfig();
$transformerConfig->enableLastDayOfMonthFix();
$transformer->setConfig($transformerConfig);

$rule = new \Recurr\Rule("FREQ=DAILY;COUNT=1;WKST=MO");

$startDate = new \DateTime();

$startDate->setTime($startDate->format('H'), $startDate->format('i'), $startDate->format('s'), 5);

$rule->setStartDate($startDate, true);

print_r($transformer->transform($rule));

// 2018-12-25

$startDate->setTime($startDate->format('H'), $startDate->format('i'), $startDate->format('s'), 0);

$rule->setStartDate($startDate, true);

print_r($transformer->transform($rule));

// 2018-12-24

So, if the startDate contains any microseconds transform will be incorrect
