Individual parts (e.g. year and month) of the add time

Individual parts (e.g. year and month) of the add time

Hello,

is it possible to query individual parts (e.g. year and month) of the add time?

We want to name our PDF documents of a sent form with it.

If I use it just like that, the filename contains illegal characters (dots and colons).

Best regards
Jörg
