Q:
Our VC++ studio 6.0 application uses _timezone variable. Where does it get that value from? From the system clock or msvcrt.dll?
A:
Environment variables are provided by the parent process, which includes system-wide settings. Also, a process can change its own environment block using the following functions: _tzset(), _putenv(), _wputenv(), _putenv_s(), _wputenv_s(), SetEnvironmentVariable()
