- The Zen Timer Library
- -----------------------
-
- Revision History
- ------------------
-
- Version 2.3 - April 1996
- ------------------------
-
- - Minor fixes and updates.
-
- Version 2.2 - September 1995
- ----------------------------
-
- - Various bug fixes and updated support for Win16 and Win32 applications.
-
- Version 2.1 - Feb 1995
- ----------------------
-
- - Fixed bugs in 32 bit protected mode version
-
- - Added support for Windows 3.1 programs using the same API. Under
- Windows because the timer is virtualised, we cant directly program
- the timer ourselves. However we use the Windows timing services to
- get 1ms accuracy (not very good, but good enough for most things).
-
- Version 2.0 - August 1994
- -------------------------
-
- - Ported to 16 and 32 bit protected modes, and all compilers supported
- by SciTech Software.
-
- - Added the LZTimerLap() function, and the lap() member functions to
- all C++ classes. This highly requested function now allows you to
- read the current state of the time without stopping its current
- execution.
-
- - Moulded the library to fit in with the new source code directory
- structure for SciTech Software products.
-
- - Removed the Precision Zen Timer and associated routines (PZTimer). In
- practice we found that we never used this class, and it became a hassle
- to maintain when it was never really used. The LZTimer is generally
- more than accurate enough for the most stringent timing exercises.
-
- - Removed Turbo Pascal support libraries (we dont have the compiler so
- we cant maintain it).
-
- Version 1.2 - October 1993
- --------------------------
-
- - Ported to Microsoft C 6.0. You can now use the library with Microsoft
- C programs, but you will need TASM in order to be able to assemble
- the object files.
-
- Version 1.1 - April 1992
- ------------------------
-
- - Modified the long period Zen Timer to allow timing across the midnight
- boundary.
-
- - Added a new Ultra Long period timer for timing code that takes up to
- 24 hours to execute.
-
- - Added a new common C++ class interface to the Zen Timer library
- to abstract out the differences between the old timer routines and the
- new ultra long period routines.
-
- - Because of the addition of C++ wrapper classes etc had to make the
- library memory model dependant again.
-
- Version 1.0 - Jan 1992
- ----------------------
-
- Original version of the library including the port by Duncan Murdoch
- for Turbo Pascal 6.0 users.
