| Purpose | There are two ways to specify a date interval. The first is the most obvious. A date interval consists of a start and end DATE. Watch out for end dates without a time specification! Date specifications are 0 extended. An end date without a time is expanded to midnight that day. So the day of the end date is not included in the interval! The start and end dates must be separated by a hyphen character. In the second form specifies the start date and an interval duration. The duration must be prefixed by a plus character. | |
