Calculates the number of days from this date/time to the other date/time. In calculating the result, other is first converted to this instance's time zone. The number of days difference is then calculated ignoring the time parts of the two date/times. For example, if this date/time was 13:00 on 1 January 2000, and other was 02:00 on 2 January 2000, the result would be 1. Note that if either instance is a local clock time (type ClockTime), the result cannot be guaranteed to be accurate, since by definition they contain no information about time zones or daylight savings changes. If one instance is date-only and the other is date-time, the date-time value is first converted to the same time specification as the date-only value, and the result is the difference in days between the resultant date and the date-only date. If both instances are date-only, the calculation ignores time zones. name="other" other date/time
