TZ... Again

Hi everyone,

Just to add a (maybe) interesting item: there exists a TZCalc freeware programme on hobbes that calculates the correct setting for 
TZ environment variable as a function of your country. My machine here in France did the swap to DST correctly with the setting 
which I got from TZcalc and upon dialling to my ISP that started TimeKeeper/2 who finally adjusted the RTC.

SET TZ=CET-1CDT,3,-1,0,3600,10,-1,0,3600,3600

Of course, the offsets here (3600 for 01.00 AM) should have been 7200 (for 02.00AM) but that I could set myself.

Here is the readme that comes with the tzcalc03.zip archive from hobbes:

TZCALC - A program for calculating the TZ environment variable.
Version 0.3 (tzcalc03.zip) 

(This program was formerly included with time868f.zip)

The TZ (time zone) environment variable controls the 
interpretation of the hardware clock. While this information
is documented elsewhere, the information is cryptic and
difficult to use. Hence this program....

This program calculates the TZ environment variable from
settings on the screen.

Installation:
1. Unzip the .zip file into a new directory in a convenient
place.

2. Run the program. Follow the notes on the screen.

3. If needed, copy the calculated value to your config.sys

If you find an error (there are some), please let me know. If
possible please include a URL for a web page where the correct
information may be found.

This program is free, but a picture postcard or an email
note is appreciated.

I hope you find this useful.
