The Energy Policy Act of 2005 law took effect on March 11 and DST started three weeks earlier and will end one week later for most of us.
Does anyone know where I might find TZEDIT.exe, applicable for a Win95B and Win98SE in the USA?
The life cycle for these two OS ended, of course, before Microsoft could write a patch to correct the time zone start/end dates to the new law.
At one time this Microsoft time zone editor, much easier and possibly safer to use than REGEDIT for modification of the system registry for the starting and ending dates of daylight time, was included in Microsoft's Power Toys for the respective OS. I suspect that a separate routine was applicable for the two OS; I know that TWEAKUI for the 95B could not be used on the 98SE.
Or, does anyone know the REGEDIT steps and code to make the change in those two OS?
For the time being, in order to continue to use the clock setting program NISTIME-32.exe, I have moved my time zone on those two OS from Eastern to Atlantic, and unchecked the automatic change to daylight time box so that the hour won't again move ahead in April. This fix works fine, as long as I remember to move from Eastern to Atlantic in March, then Atlantic to Eastern time in November, but modifying the system registry requires only one change.
Incidentally, some of you who are not using either NISTIME-32.exe, or W98SE or W95B may be interested in this data:
1. NIST telephone talking clock is reached at 303-499-7111. Accuracy probably 75 ms in continental US and dependent upon telephone delay caused by the routing of your call.
2. NIST telephone digital time service is 303-494-4774. Accuracy probably 5 ms if you use it in measured delay mode.
3. WWV and WWVH at 5, 10, 15 MHz accuracy probably no worse that 750 ms due to effect of the ionosphere, and sunrise and sunset are worst.
4. Internet time service is probably accurate to within 10 ms provided you have a reasonably good network connection at your end. With a bad local connection the performance can be just plain terrible!
In general, all of these services provide much better than 1 second accuracy in almost all conditions.
