Date arguments are converted to (seconds since epoch UTC, timezone
offset), which matches the internal storage format.

Comparisons are made only on the seconds field of that tuple.

For date ranges, "Dec 12" is converted to "Dec 12 00:00:00 to Dec 12
23:59:59". Similar conversion apply for "Dec 12 04:00", "Dec", and "2006".
