There is no proto_tree_add_item() that will directly do this for you (that I'm
aware of).  However, you could:

1) Read those values, populate a "struct tm", then make use of strftime() and
add the resulting string to the tree using proto_tree_add_string_format[_value]()

2) Construct your own value strings for month, then format your own string into
a buffer and add the resulting string to the tree using
proto_tree_add_string_format[_value]()

3) Read those values, calculating secs and nsecs for an nstime_t structure, then
call proto_tree_add_time_format[_value](), or

There might be some other alternatives.
