I see your problem now as this looks suboptimal in my opinion too.

I don't want to hold you up with this nitpicking, but what if you saved the 
incoming convert_int96_timestamps constructor parameter to a member of 
ParquetTimestampDecoder (defaulting to false)? Then you don't have to pass it 
as a parameter to GetTimestampInfoFromSchema() and this part of the code would 
look cleaner.
What do you think?
