+    Support gogoproto.stdduration option. (#35)
+    
+    Support `gogoproto.stdduration` gogo proto option that generates plain `time.Duration` as proto field via implicit conversion from gogo's `google.protobuf.Duration` proto.
+    
+    Example usage:
+    ```python
+```
+Here's what the run looks like:
+```
+|S|spacey@masonjar:~/go/src/github.com/pcn/reproducer$ ./reproducer time_reproducer.sky 
+panic: TypeError: value <google.protobuf.Duration nanos:500000000 > (type `google.protobuf.Duration') can't be assigned to type `"time".Duration'.
