I have data with a DataFrame that goes back to 1949. I imported it from a csv into a hdf5 using HDFStore. That went fine, but when reading from the HDFStore to get a DF back, I get the below stack trace. When looking at the data in the store I see that the index has negative values for preepoch times...
ValueError: timestamp out of range for platform localtime()/gmtime() function

Any guidance would be most appreciated.
