Original request:

I want to have a default value for datetime field wich is 90 day in the future.
I have set the enddate and future propperties to true.
I tried the value "now+90" but this gives an error during validation. Is there a way to calculate an offset of n days (or n seconds)?

Might be you can make a link to a variable like requested in #263

[rallek]

If the future property is set you can add automatically a variable for the offset a explained in #12

This is now possible (for 1.4 targets) using the new validatorAddition option.
More details in #640.

For the example above you would use a value like GreaterThanOrEqual("+90 days").
