generalizing for odbc
improved odbc compliance (SQL_TYPE_TIMESTAMP)
trying to clean up a few things:
- generalize some DbPointRecord functionality
- allow local and utc time formats in scada
- speed up some isPointAvailable testing
another speedup. ScadaPointRecord now uses its base-class implementation as a mem cache.
a bunch of this should be generalized to DbPointRecord
circular buffer stable - good speedup
also generalized some db point record caching (using base class)
reset implemented
Adding Sine time series. 24-hour period, 10 minute regular clock by default.
more intelligent caching
- also, fixed an elevation offset bug in tank.cpp
extra check and a note
