Hi am trying to transfer the %year% tag [YYYY] and the %date% tag [DDMM] to %releasetime% tag.

I was able to do that using the format value action but i have a problem, %releasetime% tag obviously is in wrong format [YYYY-DDMM]

I want to create an action which will result the %releasetime% tag to be formatted in [YYYY-MM-DD]

That is the correct approach. Try  
Format string: `%year%-$regexp(%date%,(\d\d)(\d\d),$2-$1)T00:00:00Z`
