Look for the typical sequence:

... RtlLocalTimeToSystemTime ()
...
    gmt = time(NULL);
    bias = TIME_GetBias(gmt, &daylight);

TIME_GetBias(time_t utc, int *pdaylight)
    ...
    ptm = localtime(&utc);
    ptm = gmtime(&utc);
    ret = last_bias = (int)(utc-mktime(ptm));

I my understanding mktime(gmtime(time(NULL))) == time(NULL)
