Hello,

I am working on an issue related to Brazil timezone. Our code reads the DST rules from windows registry instead of tzdata.

My question is -- how do I determine whether the windows system has applied the latest timezone DST rules from the following registry? I don't know how to interpret the binary data

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones




Any advice is appreciated.

Thanks,

Florence
