[Solved] Adding KB972423 using TZChange.exe

[ricktendo64]

Hello new "Optional" Daylight Savings entry has come out via MS Fix it named KB972423 and I was thinking there has got to be a way for us to do it VIA tzchange.exe tool

Here is what I got so far, the colored ones are the stuff I dont have a clue what to put there

"%11%\tzchange.exe /A ""Bangladesh Standard Time"" /S 6 5 3 23 0 0 0 /E 12 4 5 23 0 0 0 /D -60 /R 0 /B 270 /T ""Bangladesh Standard Time"" /L ""Bangladesh Daylight Time"" /N ""(GMT+06:00) Dhaka"" /G /I 2147483731"

Red = Need help with these, no clue what to put
Yellow = Not sure what they do but certain what to put there

So anybody I am glad to hear your expertize or thoughts

/?   Help

BTW tzedit.exe helped me find allot of values of what to put

Edit: OK I deduced that those numbers are probably for the Map display to move to the correct section

Edit2: Nope I think I was wrong, I think the (GMT+XX:XX) is probably what moves the map

Edit3: I have managed to get the tzchange.exe to make the exact same hex value for the TZI entry through messing around with different values (keep in mind I dont know exactly what those three mean) here is the final working tzchange switch

Code: Select all

"%11%\tzchange.exe /A ""Bangladesh Standard Time"" /S 6 5 3 23 0 0 0 /E 12 4 5 23 0 0 0 /D -60 /R 0 /B -360 /T ""Bangladesh Standard Time"" /L ""Bangladesh Daylight Time"" /N ""(GMT+06:00) Dhaka"" /G /I 2147483731"

Update 5eraph cracked it, all you have to do is divide/multiply the offset and 60...also the Plus and Minus symbols are reversed for example

-300 if the timezone is +5:00

300 if the timezone is -5:00

300 Divided by 60 equals 5

BTW the final tzchange switch on the end was correct, with 5eraph's calculation I was able to confirm it

As discussed im IM, rick and I determined that /B refers to the GMT offset, between -12 and +13 hours, described in minutes. Just reverse the sign.

Thanks go to rick, he did most of the work in figuring it out and verification.
