alternative is to pimp dates c'tor:

if (is_string($date)) {
$date = trim($date, '"');
// Accept Unix timestamps passed as numeric strings.
if (preg_match('/^-?\d+$/', $date)) {
$date = (int)$date;
}
}

No, that's broken behaviour - ints are supposedly unix timestamps, '20010203040506' should NOT be treated the same way.

I can limit "strings are timestamps" to (optional -) + exactly 11 digit chars and still we won't be too happy with it.

Lesson learned: Constructors should eat typed objects but we will not purposefully change Horde_Date in lib/ now. Going forward, best feed DateTimeInterface objects into Horde_Date (if feasible, beware of timezones) or cast to int when you are sure it's a timestamp.
