How to manipulate the date in idoc scripting?

Question

how can we manipulate date in idoc scripting? How to retrieve the year, month, date from the date? How can we update the year of the particular date in idoc scripting.

Answer 1

There are a bunch of date / time functions that you can find in chapter 5 of the Idoc Script Reference (the bible for this sort of thing)
For the sort of things you need to do I would recommend you look at formatDateWithPattern()
for example to retrieve the year of 'now'
<$year = formatDateWithPattern(dateCurrent(),"yyyy")$>
month
<$month = formatDateWithPattern(dateCurrent(),"MMM")$>
the patterns for the same rules as Java date formats (unsurprisingly)
If you want to update the year then I think you need to build the date as a string and the use the parseDate or parseDateWithPattern functions to actually create something that Idoc will recognise as a date object.
