I checked this example and your script - it is not correct, because you
compare separately year, month and day of document with current date - year,
month and day-100. But if, for example now is 02 january, your script give
uncorrect result, becase I also should change year and month (and year),
then I want to get date BEFORE 100 days of 02 january.
Need to make arithmetical operations with dates and these operations should
consider also possible transitions of month and year when day changed ...
In any case - thanks!
I found the answer - need to use special velocity object $datetool
Example:
#set ($d = 5) - days interval which I need
#set ($ms = $d * 24 * 60 * 60 * 1000) - Calculating internal in
Milliseconds
#set ($calendar = $datetool.getCalendar())
#set ($currentTime = $calendar.getTimeInMillis())
#set ($targetTime = $currentTime - $ms)
#set ($void = $calendar.setTimeInMillis($targetTime))
#set ($targetDate = $calendar.getTime())
#set ($targetYear = $datetool.getYear($targetDate)) :get year of
a date = currentdate - 5 days
#set ($targetMonth = $datetool.getMonth($targetDate) + 1) :get month of a
date = currentdate - 5 days
#set ($targetDay = $datetool.getDay($targetDate)) :get day of
a date = currentdate - 5 days
and after this, in a hql searching, I can compare this year, month, and day
with documents year, month and day ...
