Parameter Description
startDateTime The date and time of the beginning of the interval.
endDateTime The date and time of the end of the interval.

Return Value

DateTime interval in UTC time.


$(Interval("1/31/2014 11:36 AM", "2/2/2014 11:36 AM"))

returns the interval between the two dates.

Although the values for the startDateTime and endDateTime parameters are in UTC, as with all DateTime literals in expressions, these are written in the locale and time zone of the current user.

$(mydate during Interval("1/31/2014 11:36 AM", "2/2/2014 11:36 AM"))

returns true if mydate is between the two DateTime values, inclusive.  This function returns false otherwise.

$(mydate during Interval(BeginningOfMonth(-3), EndOfMonth(0)))

returns true if mydate is in the four-month interval between the start of the month that was 3 months ago and the end of the current month.
