rtc_tm.tm_mon = rtc_c_value[2] - 1;
rtc_tm.tm_year = rtc_c_value[0] * 256 + rtc_c_value[1] - 1970;

------------------------
1. After complie the program above, the advise "(ULP 15.1) Detected consecutive bitfield assigns. Recommend using bit mask instead" occured 6 times during the line of "rtc_tm.tm_min = rtc_c_value[5];" and "rtc_tm.tm_isdst = -1;", But I can't understand where I have used the bitfield assigns?
2. In time.h, it shows below:
-----------------
struct tm
{
.....
int tm_mday; /* day of the month - [1,31] */
...
int tm_year; /* years since 1900 */
.....
};
----------------
But actually I must adds current day of the month with 1 and minus current year with 1970 to get correct UTC time. I've read the link
But I can't find where to add or remove __TI_TIME_USES_64.
