- CHANGES IN TIMESET 7.21
-
- This version of TimeSet, the leading program for setting computers to
- atomic time services by telephone, fixes a few minor flaws that became
- apparent in Versions 7.10 and 7.20 and also adds new features:
-
- o The inability of version 7.20 to work with nonstandard serial port
- addresses and IRQs is corrected in version 7.21. (My thanks to Bob
- Germer and Alex Walter for helping me track down the problem.)
-
- o The feature for automatic reconfiguration for Daylight and Standard
- time in North America has been fixed. This feature, first introduced
- in Version 7.10, failed to work in that version, requiring users to do
- the reconfiguration manually. Like Version 7.20, 7.21 extends
- automatic season adjustment for TimeSet to users who follow the
- British and European systems for Summer Time and Winter Time. These
- three automatic season options plus the option for manual season
- adjustment (or no season adjustment) are available by toggling at
- TimeSet's configuration screen.
-
- o Occasional erroneous calculation of before/after clock errors for the
- call log file TimeSet.Log has been fixed.
-
- o An optional modem initialization string for Zoom high-speed modems has
- been hard-coded into TimeSet 7.20's configuration procedure. If you
- have that brand of modem, just toggle to it with the right or left
- arrow key; the manual, TimSet72.Doc, tells you what it looks like.
- (The decision to hard-code that string option was made because Zoom
- modems have probably generated more configuration headaches for TimeSet
- users -- and for us -- than any other brand.)
-
- o Some new command line switches have been added. /0p delays automatic
- pulse generation at the parallel port based on freshly set time until
- after a countdown to zero seconds (i.e., the start of the next minute).
- This is for people who want the pulse to start or stop some external
- process on the minute. The new /0c command acts similarly but only
- provides the countdown, with no pulse at the parallel port; it's
- mainly to help people synchronize a watch or clock to the new time.
- /fs defeats the "parting curtains" screen effects if snappier action
- is desired. /s skips the opening "starry field" logo screen and takes
- the user directly to the action menu.
-
- o Result codes are now provided for those who run TimeSet in automatic
- mode from a batch file and want to use the DOS ErrorLevel command to
- initiate specific actions based on the code returned.
-
- o Like version 7.20, TimeSet 7.21 is interactive and compatible with
- Version 2.54 of Tom Becker's RighTime -- a shareware program that
- learns and refines a correction for computer clock drift so it can
- apply small corrections throughout the day to keep the clock highly
- accurate (as little as a fraction of a second of error after several
- days).
-
- o TimeSet 7.21 is the most accurate and precise version yet. With
- RighTime 2.54 installed for .01-sec clock resolution, tests showed
- repeated agreement within .01 second on before/after clock readings
- when line delay calls from this Seattle suburb were rotated in quick
- succession among atomic clock services at the Naval Observatory
- (Washington, D.C.), National Institute of Standards and Technology
- (Boulder, Colorado), Swedish National Time Service (Stockholm), the
- Technical University of Graz (Austria), and Tom Becker's TimeGen
- service in Dallas (which is regulated with RighTime 2.54 and updated
- regularly from an official atomic time service). In several tests,
- perfect agreement was often found among all four services. This is
- remarkable precision in line delay measurement and compensation,
- considering the varied distances and signal paths involved (land
- lines in the U.S. and satellite links abroad).
-
- o The time data string generator program TimeGen has been significantly
- upgraded in Version 3.10. TimeGen now automatically writes information
- on each TimeSet call to its own log file, called TimeGen.Log. The data
- logged include the date, time the call was concluded, seconds online,
- and the type of clock setting action (line delay measured/not measured
- or call aborted). If your version of DOS is 3.00 or later, this file
- is automatically maintained in TimeGen's own directory whether you are
- in that directory or not, provided TimeGen's directory is on your system
- path (users of earlier DOS versions will need to run TimeGen from its
- own directory in order to keep new log files from being created in
- several directories). A new companion program, TgSumm, can process the
- data in TimeGen.Log to prepare a summary both by date and cumulatively
- (to use it you must run it in the same directory that contains
- TimeGen.Log). The summary is simultaneously displayed on the screen
- and stored in a file called TgSummry.Log. Both TimeGen.Log and
- TgSummry.Log are standard ASCII files and can be reviewed with the TYPE
- command or with an editor or listing program. TgSumm can log up to
- 10,000 hours minus 1 second of cumulative connect time (9999:59:59).
-
- If you want to see a demonstration of TimeGen in action, edit the
- TimeGen phone number line in TimeSet 7.20's configuration screen so
- it reads 1-214-869-0344, save with F10, and press Alt-T or T at
- TimeSet's main menu to initiate a call to Tom Becker's TimeGen service
- in Dallas.
-
- These are just the major changes. Scores of additional changes -- so many
- we've lost track of them -- have been made in TimeSet 7.20's code to make it
- the best and most accurate version yet.
-
- Thanks for supporting shareware! That support is what makes continued
- development of TimeSet possible and desirable. If you haven't yet become a
- registered TimeSet user, please don't put it off any longer. The file
- TimSet72.Reg is a registration form that you can easily send to your
- printer using the DOS command, COPY TIMSET72.REG PRN, then fill it out and
- mail it to us with a check for $40 U.S. Alternatively, if you live in the
- United States and would rather be invoiced, you can upload your registration
- with a toll-free call to our electronic mailbox using the enclosed TsReg72
- program. On receipt of your payment we'll send you a bound and illustrated
- printed manual, any new version or upgrade of TimeSet and its associated
- programs, technical support by telephone, and a substantial discount on the
- next version of TimeSet. Tom Becker has also authorized us to include an
- evaluation version of his RighTime shareware clock-regulator program on the
- diskettes we send to registered TimeSet users.
