Set the local time period information used by the localTimeOffset method to that for the time zone in the TZ environment variable at the current UTC datetime. Return 0 on success, and a non-zero value otherwise. This method is not thread-safe. The behavior is undefined if the environment changes (e.g., a call to the putenv POSIX function) during the invocation of this method.
