On 32bits platforms "struct timeval" or "time_t" are using u32 to code the date, this cause tools like "date" or "hwclock" failed even before setting the RTC device if the date is superior to year 2038 (or 2106). To avoid this problem I add two RTC tests files which directly use RTC ioctl to set and read RTC time and alarm values. rtctest_setdate allow to set any date/time given in the command line. rtctest-2038 perform a basic test by writing 1-1-2200 in RTC time and alarm and checking that the read back values are correct. Finally that had allowed me to test and fix rtc-st-lpc driver.
