| Purpose | There are three 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, the end date is omitted. A 24 hour interval is assumed. The third form specifies the start date and an interval duration. The duration must be prefixed by a plus character. The start and end date of the interval must be within the specified project time frame. | |
