Unix to UTC conversion in formula of table widget

Unix to UTC conversion in formula of table widget

Hello,

Is it possible to convert the value of a variable which in this case is a UNIX timestamp into a UTC Date? I need to do this within the formula section of a dynamic table column. 

My scenario:
variable = data_array_timestamp, value = "1681603200" which is a Unix timestamp. This value is a timestamp that will be older than the timestamp of the payload, therefore using the given Date & Time column of the table will not work for my use. 

I appreciate any help with this!
