You could either write a function or an edit input (specified in Property rule-form)  or a Java step in an activity to convert the string

2017-03-29T00:00:00+0000

to GMT

20170523T163400.000 

depending on how you get/enter the first string value and where it should be transformed.

A simple way would be to get the substrings of the main string without special characters and concatenate them for GMT format.
