// TSUtil - class for static time series functions
//------------------------------------------------------------------------------
// Copyright:	See the COPYRIGHT file.
//------------------------------------------------------------------------------
// Notes:	(1)	This class contains static functions used to manipulate
//			time series.  Putting functions here rather than in
//			TS, for example, makes it easier to do development
//			because changes to TSUtil do not require a recompile of
//			the derived classes (the way that a recompile of TS
//			would).
//------------------------------------------------------------------------------
// History:
// 
// 05 Jan 1998	Steven A. Malers,	Created initial version of class.
//		Riverside Technology,	Move "static" functions out of TS to
//		inc			here to simplify development.
