@clairblacketer,

I see that measurement table contains both measurement_time and measurement_datetime columns, whereas the first one is not mentioned in specification (OMOP_CDM_v5_3.pdf) and seems to be deprecated. Do I miss smth?

measurement_time              VARCHAR(10) NULL ,
measurement_datetime			    TIMESTAMP		NULL ,

measurement_time was an addition in 5.0.1, I added it back in to 5.3 because it was removed from 5.2 and therefore not backwards compatible. I will fix the documentation to reflect this
