What Hoss said, and in addition somewhere some custom code has to be translating things back and forth. For dates, Solr wants YYYY-MM-DDTHH:MM:SSZ as a date string it knows how to deal with. That simply couldn't parse as a float type so there's some custom code that transforms dates into a float at ingest time and converts from float to something recognizable as a date on output.
