Partial implemenation of load-Analysis code.

Modified storage of TIMESTAMPTZ to ye olde workaround:  store milliseconds since the Unix epoch.
It seems that, even in 2015, we still haven't got a reliable mechanism to load TIMESTAMPTZ
via JDBC, unless you roll your own converter from java.sql.Timestamp.toString(), and that is
way too brittle (and more work than I feel like engaging in).
