WITHIN(time1, time2)

Returns a Boolean TRUE if the time lies within all the 
ranges defined by the elements in time1, time2. 

If you omit an element of time from time1, it is assumed 
to have the lowest value in its range. If you omit an 
element from time2, it is assumed to have the highest 
value of its range. If you specify a year in time1, you 
must specify it in time2. 

The ranges for elements of time are as follows: month 
1-12, day 1-31, weekday 0-6, hour 0-23, minutes 0-59 
and seconds 0-59. For the result to be TRUE, each 
element in the time must exist in the corresponding 
range that you specify in time1, time2. 

For example, if time is GMT 2005 May 10 10h 15m 
30s, and it is the second Tuesday of the month, you can 
specify the following (evaluation results are in 
parentheses):

• . . .within(GMT 2004, GMT 2006) 

(TRUE) 

• . . .within(GMT 2004 Jan, GMT 2006

is in the range for February to December)

(TRUE, the second Tuesday lies within the range of 
the first Sunday through the third Sunday)
