Unix timestamp converter

Hello, 

is there a unix timestamp converter in RM? For example I have the value 1473415924 and I want YMDMS. Or do I have to do it with excel first?

edit: I found a forumla for excel. Can I somehow use it in RM maybe "Generate Attribute"?

 "("+dateupload+"/86400)+25569+(n/-5/24)" can I
